The axles themselves is what makes up the length differnece, not the housing

83-85.5 got the mustang width housing and axles

85.5-86 got the tbird width housing, but the mustang width axles

87-88 got the tbird width housing, and tbird width axles

NO......

First go back and read THIS THREAD There are measurments there, and in another therad that is referenced in that one as well.

This is how it is.....

ON the 7.5's

83-85.5 - Mustang housing - TBird axles
85.5-88 - TBird housing - TBird axles

87-88 8.8 - Mustang housing - Tbird axles.(same width (housing and overall) as the 83-85.5 7.5 set-up)

The rear track width on a TBird regardless of year is 58.5"

The rear track width on a Fox Mustang (SVO and 93 Cobra excluded) is 57"

Rear track width on an SN-95 Mustang (94-98) is 58.5"

The axles in a Tbird and SN-95 Mustang are 3/4" longer than the Fox Mustang stuff.

The ones who suffer from all the oddball problems are the 86-88 7.5-reared cars...due to the longer housings.

OK, here's a question...

What are YOU wanting to accomplish with what you have?

That would be a better way to go about this, instead of this continual rehash.

I take it by your screen name you have an '86. What are you wanting to do? You are stuck if you want to do something like install 87-88TC disks or the like due to the wider housing.

As has been mentioned, if you want something with the same track width, and disks, get a 94-98 Mustang rear assembly (complete).

What do you want to do?

Just for clarifications...the info on coolcats.net is for the housings, not the axle shafts. I purposely don't mention track width differences on the site because of the potential confusion.

Does a V-6 Mustang (94-98) have an 8.8 axle?

Nope, 7.5. At least not from the factory.

If an SN-95 mustang rear end is a bolt in solution, then problem solved. V8/GT rear end.

In the end I'm going to need a rear end to handle a reasonably built fuel injected 347 stroker motor. Since I'm starting with a daily driver car I have just purchased, I'll finish the motor and build a good AOD before I start. But easy swaps, like rear end, suspention upgrades (sway bars, ect) I can do in the meantime.

Since I want a limited slip, I'm stuck with an 8.8, no biggie since it's stronger.

Only reason I'm not doing all this to a mustang is because I'm tired of the higher insurance rates and all the cops that love to eyeball the mustangs, firebirds, ect. Besides, I also now have a usable back seat.

the sn 95 rear will have 5 lug obviously. youd either have to swap out axles, or upgrade the fronts to 5 lug...figured it would be worth mentioning...

also...

ive got the 8.8 TC rear stripped and ready for PC. i measured out my 5 lug mustang axles just to double check and there just about the same length as the turbo coupe ones from the face of the lug plate to the end of the splines...

the 7.5 is still in the tbird. i hadnt realized for whatever reason that the 7.5 might be a different in width compared to the turbo coupe rear diff.

so, whats gonna happen? is the 8.8 gonna bring my wheels even tighter into the car? i never liked how far they were inside of the wheelwell anyway. no biggie as i know it will work fine and i can go from there but now im curious....

If the axles are the same length, then how would they bring the wheels in further?

Your track width is going to be the same as it was with the 7.5. That is ASSUMING the Mustang axles you have are SN-95...but you also stated they are the same length as what was in there...so....you should be fine.

cool,thanks chuck.. i meant the differance between the 7.5 thats on the car and the 8.8 with the sn95 axles... for some reason i never gave a though that the 7.5 could have a different track width than the TC8.8.....i never compared the 2, just assumed they would be the same.

The axle length and track width never changed on the Tbirds, and is the same as the early SN-95 stuff (I can't speak for the 99-04 stuff). You just can't use the SN-95 axles in your 86-88 7.5 housing, but you can use them in an 83-85 one (<---done it twice).

You're using rear disks correct? (just making sure)

yeah, M2300-K. i just dont want any supprises when it comes to putting the car together. im watching mansons progress cause im about to order the same front arms. heres my parts list so far:
turbo coupe 8.8/3:73
m-2300-k
che rear adjustable lowers, fixed uppers
new bushings in the housing
M-3075-D (2003 cobra front arms)
prothane or energy isolators/boots swaybar bushings, endlinks (did i miss anything?) etc
mustang bullit springs front and rear as well as tokiko dampaners
MM CC plates and SFC as well as your cross braces...thanks a million BTW....!

i hope everything works soundly together. im not looking to make the car handle like a race car, but as well as or better than say, a turbo coupe. i dont think i realy missed anything but if i did feel free to let me know...lol.also, if you would have changed anything i wouldnt mind some input. i think i have a relitivally decent setup there...with the 17x8s im playing it safe but they should be good enough for me.

i still need to order the urathane, springs and front arms. im afraid to pull the trigger on the springs and front arms cause of mansons trouble there. i have spindles from a 2001 cobra. i dont want to have to punch someone in the face...!

later on i want the upper and lower torque boxes re-inforced, and maybe rocker reinforcements. im also pondering a 6 point but i just dont see the car ever being fast enough to require one. they are sweet though and should hold the car together rather awesomly...
17x8 wheels with brobably just 245s all the way around

i realy hope

You shouldn't have any issues with the rear and the brakes.

Seems like the intelligent thing to do if you use the SM-95 rear would be to upgrade to 5 lug fronts also. Seems like there is a better selection in aftermarket wheels, not to mention the newer 5 lug mustang wheels. Also if you have the option of upgrading to rear discs, why would you not do it? Yeah, you need a different macter cyl and porportioning valve, but easy to get from the same donor car. Only other issue is parking brake and even that is almost always easy to solve.
