shouldn't have anything to do with the internals, the gears are set to a case not to the car so if the whole case is swapped it should be fine, i've done it before as well like on my 83 i pulled my 8.8 from my 88 and put that in there no way was i wantin to stick with the 7.5.

 

Gotcha, it's possible I have it confused with something else.

 

you will have to notch the backing plate mount on the axle to clear your ABS sensors IF you are swapping in a fox 8.8

 

I think they all have SN95s...

 

well the diff i'm getting is from a new edge, my friend got it for his drag fox, so i'm assuming that i shouldnt have to do much to make it fit mine other than put my axles in. otherwise my diff is going into a 86 gt.

 

Good luck with the 4.10's! ...will wake your car right up!

 

I think the New edges have 4 wheel ABS which mean's the brake lines are routed differently but now that I think about it, it may not be a problem. Also, your track width will be 1.5" wider than what you have now, again, it's probably a non issue running that wide on the SN95 but those axles are 1.5" wider each side than the Foxes.

 

i went from 2.73's to 4.30's in my fox.... WOW thats all i have to say. O and i have a 5 speed to, that sees some highway cruising, it isnt as bad as a lot of people make it out to be

 

Nah, It's just pull out the entire differential and do the swap

 

hes using his stock axles... there wont be any change in his track width
