Rear end upgrade??

I never actually eyeballed a 73' up slant with a stick. While surprised, I can see why they upgraded the rear with the 3spd. Thanks guys.....I'm never to old to learn. :thumleft:

P.S. I'm curious as to if it's a frt. disk car? Looks to be a big bolt pattern also?


Since drum brake 73' cars had small bolt patterns and 7.25" rears, does that mean the manual slant's required frt. disks if they indeed came with a 8.25? Just looking for knowledge...
