Went to the pic-a-part in 2006 looking for a new larger battery tray for the Mustang. For less than 20.00.
Car is a 79, battery on ps. 56 group std. Hard to find. Replacement trays are not bigger. 84 prob same.
Wanted to install group 96R like the new Mustangs have.
1" wider than 56, 2" lower. Group 58 similar, 1"+ wider. 65 too big.
Pick was based on what battery groups were least expensive for size and readily available anywhere.
Has lower profile, high power capy. More hood clearance in case battery came loose from crappy roads here.
Had the dimensions with me. Had to find a vehicle with similar shape battery tray only bigger.
Mustang one is flat and has additional risers/support underneath to contact the frame rail.
Easiest one to pull was from a 80's? Dodge Caravan. Was easy to remove, plastic, fasteners not rusty. Nothing special.
Some trays are welded in so those were not an option.
Was a test install, planning on getting something else if it did not work out. Had to mod it a little to install.
Think i bolted some wood under there to support it.
Prob are better matches made since then, but is working fine. Cannot get a bigger tray in there.
Battery hold downs should match. I use ss fasteners so rust is not a problem 5+ years later when removing battery.
The hold down bracket hole cracked, so may be looking to replace it. Or just fix with different hold down bracket.
Lots of bigger cars, trucks use bigger batteries and trays. If car is not for show, anything goes.
