    Default 8.8 brake line mount

    I gathered all the necessary parts for the 8.8 swap into my 83GT. I got the aero mount with a long piece of hard brake line that goes down the trans tunnel. It seems the factory used pop rivets to mount the piece used to attach the flexible line to the hard line. It's not the floor, so I cannot get inside that location to use nuts and bolts. I noticed some you fellows used nuts and bolts. How did you guys mount it? Thanks

    My stock '85 flared hard to flex hose mount was held in with sheet metal screws from the factory. I drilled and chizzled the rivets off the banjo mount on a '93 mustang and just re-used my sheet metal screws to mount it under the car. The fastener pattern on the '93 banjo fitting mount was exactly the same. This is the stock location for flare line junction on my '85.

    On my 86 I just ran a tap through the sheetmetal and used some 5/16-18 bolts that were about 3/4" long. They have been in there over a year.

    Rivets. Screws and bolts rust, the come loose, they fall out, they strip, etc. Rivets just pop in, aluminum doesn't rust, and they come out really easy with a drill.

    Both you and Domino look to have this bracket installed on the same (passenger) side. The SN95 rear I have has the flex line on the driver's side yet on the 82 the line went to a bracket on the passenger side. I've read a little about maybe having to run a new hard line ( for a ?? Year car) that goes to the drivers side then possibly use an SN95 bracket in this location. What kind of adaptor did you use in your pic to accommodate the banjo bolt or am I missing something? Something that seems simple enough is throwing me a curve ball

    Reverse your perspective. See the upper control arms? The bracket mounts just to the driver's side of center, the flexible hose is from a 86-up V8 car and mounts to the driver's side of the axle housing. The hardline(s) came from 86-up V8 cars. I replaced everything from the passenger's side of the firewall up front to the wheel cylinders in back, with parts store and reproduction parts. More details and part numbers are on my Cardomain page. http://www.cardomain.com/ride/242602...-trims/page-7/

    We mounted ours with 1/4" stainless hex head sheet metal screws. Cant remember how long but probably no longer than 1/2".

    For my car, the new SN95 rear end, as I stated, already has the the lines on it and they are to the drivers side of the pumpkin. As shown are the existing AN? flex connection and the newer flex connection (which I assume is newer and different than the 86+ that jimmy has?) that as well as my current location for the hard line and the bracket location which is way to the passenger side. I wasn't expecting to have to change out the hard line, but it is looking like I may have to from what I am seeing you others talk about as well as get the new bracket. I was hoping I could modify, bend and extend existing, but that may not be the best way. I guess my question is which is which year would I get for a hard line: the 86-93 as you did jimmy? and does this have the right connection to adapt with a banjo bolt as I see you have?

    Thanks for your help.

    Nice cardomain link btw jimmy!

    The SN95 rear in your pics, has the same brake hose as a Fox body with dual exhaust. They moved the hose on dual exhaust cars, because if it's left on the passenger's side it'll rub on the tail pipe.

    The brake line anchor has a fitting, the brake hardline screws into the fitting, and the banjo fitting from the axle bolts into the other side of the fitting. And of course the hardline from the firewall back to the rear of the car is different since the single exhaust hardline ends on the passenger's side, and the dual exhaust line ends up over the driver's middle of the rear axle.

    What I did was buy a reproduction line for a 87-93 V8 Mustang. The alternative would be to use a coupler and a new piece of brake line to extend the existing line to the late brake anchor. Or if the car doesn't have dual exhaust, use the single exhaust brake lines on the axle and leave the body side lines alone.

    There is more info and pics on the exhaust/brake line changeover on page 3 of my Cardomain page... These pics might help a little...

    On Foxen that didn't originally come with tail pipes on each side, the brake hose connects over
    on the passenger side. When relocating the lines to work with dual pipes, you can extend the
    existing line using a 90-degree flare nut fitting and a piece of brake line to reach over to where
    the factory put the banjo fitting on the '85-up cars, or you can run a complete new line using
    donor parts from a car that came with the dual pipes.

    For an example of the 90-degree fitting you would need to extend the existing line, look at how
    the brake line connects under hood on the passenger side of the cowl where it heads into the
    passenger compartment.

    Jimmy2.3Mustang, when you ordered the repro brake line, did it come with that fitting? If not, where did you get it? I had to track down a guy that was parting out a V8 dual exhaust Mustang to get the fitting. Ford dealer says they can't get it, and no parts store has anything of the sort that I've found. I did spend some quality time at Napa the other day and we came up with replacing the banjo bolt with metric, cutting and reflaring the line with a metric nut, and then you can use a metric union. From what they had, they couldn't find a SAE banjo bolt that would match up, and the one I had from an SN95 rear caliper was oddball M10-1.5" thread.

    That said, I do have the fitting now from the parted out car, I'm just wondering for anyone else that may need to track it down, so they don't have to go through the same crap I did. Or if i need to replace mine for whatever reason.

    This explains a lot with the single/dual exhaust applications. I may do as you suggest and just advance the existing line. This seems easier to me rather than re-run a new line due to them crossing and running underneath my welded in sub frame connectors. The fun part will be finding all of the right adaptors, connectors, fittings and brackets.
    Thanks a ton all.

    I got the fitting, clip, and hanger from the classifieds here, essentially a parts car. There's probably some magical hydraulic hardware store that would have the fitting, but since a person needs the hanger anyway, it's probably best to get the fitting from the same donor car.

    Extending the stock line is probably the cheapest and easiest way to get the job done, but I'm a bit lazy about fabricating, and preferred to use factory parts. It was a bit of a pain, but it looks like it belongs...

    My car is an 86 and the holes to mount the bracket were already there. I took the easy way out and just extended my factory brake line.

    8.8 is in! Re-routed the bracket and brake line from aero fox, and joined with existing 83 line. New 8.8 I picked up from corral for $75 and it already had FMS 3.73's. New bearings, seals, and it's in. Only downside is with the 7.5 it had 3.08's. On the highway RPM's went from 1900 RPM's at 65mph with the 7.5, to 2300 RPM's at 65 with the 8.8. Better city driving though. Overall, great swap. It also gave me the chance to clean and paint on my 'chassis Saver' poly paint underneath. Thanks for the help!

    Awesome!

    I've decided I'm going to use the 7.5 hard lines and re-bend them to fit the SN95 8.8 rear disc set-up rather than relocate the body line and add the bracket.

    Is there a exact location the bracket goes? Other then the obvious, where the rubber line ends. Looking under car I was looking for a flat spot or something but didn't see a defined are on floor where it could go.

    Hi, do you have an 8.8 rear?

    I'm looking online for the correct bracket to convert my 7.5 to an 8.8 and I see two very different brackets available for the same years.

    Yours appears to be this one: https://lmr.com/item/LRS-2073BRKT/mu...-bracket-86-93

    And this one says it's for similar years that have an 8.8: https://lmr.com/item/LRS-2282B/86-95...ear-Brake-Hose

    I thought people were using the first link above for 8.8s... Maybe you or someone else can clarify which bracket I would need to switch my dual exhaust 82 GT from 7.5 to 8.8?

    The top one is for the chassis hardline mount, the bottom one is the rearend mount, and hose that goes to the chassis mount.
    You'll need both if you're wanting to convert to the v8 style (8. set up.
