Will a 8.8 rearend from a Thunderbird SC bolt into a Fox body Mustang? Same alxe length? Same dimensions?

I believe it will. A guy I work with, says his brother has one in his fox and it was a direct fit. How true it is, not sure.

if its a Super Coupe meaning the supercharged MN-12 style ( bigger birds with rectangle headlights) then it will not fit because it is independent rear suspension unless you plan on fabbing a setup up. If its out of a turbo coupe, it will fit but it is a lil bit wider then a stock mustang axle but has rear disc and a locking 3.73 rear under it.

All '89+ Thunderbirds had IRS.

the width is wider about .75-1" both sides

88 would be turbo coupe, disc brakes as said and 3.55 manual 3.73 auto

GT350

If it is aTurbo Coupe it fits perfect, but you will have to cut down the axel dampner brackets, easy to do, if you have Quad shocks, I installed one in my 84 GT350, plus they are a good used choice due to lack of abuse because how much could it have gone thru from a 4 cylinder?And automatics came with 3.73 Traction Loc rears.

they work great but like I said they are about .75" wider at the wheels so you can use a different off set rim if it's a issue

GT350

They are wider only if you use the disc brakes on them, otherwise they are the same backing plate to backing plateas a 7.5 in rear end, not sure about the 8.8 in a mustang, and I used a 4.5 in. back space on my Weld Pro Stars, and had enough room for 275/60with a 1/4 in to spare on the horizontal dampner.
