8.25 rear end for sale

Good Morning All,

Let me begin with saying that I'm brand new (ie...joined the forum last night) and may have lots of "dumb" questions. But I just got a 74 duster with a slant 6 that I'm updating to a 360(already found a motor and have it torn down and ready for the machine shop). With that said, I've been hearing and told a lot that I should get an 8 3/4 for my car. Would the 8 1/4 be good enough (to help with costs)?

I appreciate the help and any advice!

the 8 1/4" rear is plenty strong enough for a street car, if you don't plan to beat on it to hard
