Rear end blew, any help would be much appreciated!

I have a 1998 V6 Mustang and on the way to my new job the rear gears blew. I was thinking of swapping off my rear end from my 96, it has absolutely no play from the shaft to the wheels but it seems as though the 96 is squared off at the top mounts. Other than that I have found an 8.8 assembly I could piece together if it is possible. So, my two questions are that I cannot seem to find an answer to on the forums are:

-Can I swap 8.8's into a 7.5 housing?

-Has anyone take a 96 rear end and swapped it onto a 98?

Attached it a picture of the assembly I could pick up for $15, any help would be greatly appreciated!

You can not put 8.8 parts in a 7.5 rear end, except for the 28 spline axles and axle bearings. If anybody tells you different then they don't know what they are talking about.

Your '96 rear end should bolt right into your '98, but I think it will be slightly narrower. This shouldn't be a problem unless you are using very wide tires and are already close on the inside. I can't remember if it was '98 or '99 when they went to the wider rear end.
It was when the new edge (99-04) came out when they switched to the wider housing. I highly recommend swapping to the 8.8 rear end as it is much stronger and you will have LSD/locking differential. I have a 1999 v6 and i kept on breaking the spider gears so i swapped to a 95 8.8 axle and now my tires it further in. Nothing wheel spacers cant fix though. 98 to 96 rear end should be simple bolt on installation. no extra components needed.
94 thru 98 7.5 axles will swap. Remember, if you swap the whole axle, some have ABS and some don't. Local yards are about $125 if you pull it off a car yourself. is nationwide and has them used for about $200 with warranty. :wink:
wish I would've known sooner, I threw some 4.10's in but I have another mustang I wouldn't mind swapping out I'll keep that in mind thank you!
