Hey everyone

1. What year and model ford 8.8s are a direct fit for a 1979 Ford Fairmont Sedan?
2. Are there any benefits with the 7.5 over the 8.8?

What models and years of mustangs, explorers etc came with an 8.8 which is a direct bolt up to my '79 Fairmont sedan without any modifications?


I had a bastard teeny tiny 6.something differential and not the 7.5 which was a shocking discovery when I went to install my 3.73 Yukon Duragrip LSD kit because I thought the car only came with either the 7.5 or 8.8 and I know it wasn't an 8.8 for sure...BUT rather than trying to source a 7.5 I'm going to try and sell the kit and upgrade to the 8.8 with all the bells and whistles including 31spline axles. I think the 86-93 Mustangs share the same 8.8 rear ends but can anyone confirm that?

The plan is to buy an 86-93 8.8 housing on eBay

and rebuild it with this kit from LMR

Are there any additional parts I would need to fit to the housing?


LMR have a note about brake fitment being ONLY for Turbo coupe brakes with an adapter or drum brakes...I like the Baer SS4 5lug brake kit with the 12" rotors

but I'm not sure if they'll work on this version of 8.8, might give Baer a call about that but for now, I just wanted to confirm I'm heading in the right direction with these parts to make it a painless swap.

Right now the diff is welded and is soooooo tiny but holding, but VERY unsafe under boost.

Here's a video for attention:
