I bet it ain't.
If it is, yes it would fit. I would swap the axle tube over for ours.
They were 3.73s only in man trans zr2s. search here to get the low down

Ok Dc thanks. So if it is not could this guy Jeff down in Georgia take my aluminum one and switch out whatever is necessary to make it all good. My aluminum one is out of a 99 removed and was going to be sent down for the locker. Then I stumbled into this. I don’t mind spending money I hate to waste it

you need to read capt-n-crunch's post about twin torsens

https://www.astrosafari.com/viewtopic.p ... 9&t=124738

I'd want you to get it from him, not my bad memory.
I dunno what Jeff can do.
I'd just get a junkyard front diff, if yours is bad. To give you time to read.
I wouldn't bother with front stuff til the rear is sorted out. A locker, torsen, etc.

The time to learn is always well spent. I sorted my desire for a rear posi for under $200. A front posi will always be expensive. As much as I like to spend money, I won't be doing a front.

Search first for info on cast front diff. I could be wrong, but I don't think so, about all cast diffs being 3.73s.

Also, might want to check with the Syclone/Typhoon guys that made the torsen happen for the front differential. They were buying up a LOT of the front diffs, they might have some that ended up being the wrong ratio for them but the right ratio for you :)
