Is an 8 1/4", 2.45:1 diff housing exclusive?

Thanks for the math, AJ. It put us on the moon! My 4sp is not an OD. During my transmission overhaul, the NOS cluster gear I put in was standard, '64 vintage and at 65 MPH my /6 is purring at about 2K RPM, according to my vintage dwell/tach sitting on the passenger seat.


I love this stuff! Thanks!! I found this tire size comparison and played with it like a kid with a new toy. :D

From the recommended 15 page thread at the beginning of this thread, I've have learned the offset 2.45, 8 1/4" rear end is "special". Mom said I was special so I'd think I could relate better to this issue... I did note a comment from Prostocker273 (sorry, I haven't figured out how to reference members with the "@Name" yet) from back in 2016 stating 1995 and older Jeep 3.07 and 3.55 would fit with a carrier swap.

I'm pretty sure I could scratch build a rear end if I can access any needed special tools. I'm pretty good at following a cook book and am reasonably good at monkey see - monkey do.:p

I have to remind myself that all this started with just learning a Cheep Jherokee rear disk swap is a $350 date, and finding a leaking rear axel seal. I had a leaking kitchen faucet once that turned in to a full kitchen remodel.
:mad:
