Calling the guy today, I know I can bolt in an A Body rear from 68-72 with the UMI conversion kit but I am uncertain about a couple things. Are there any driveshaft modifications that need to be made? Also what backspacing would I have to run for the rims due to the fact that rear is wider? Thanks for any input, everyone on this forum always helps me out and I hope to one day know enough to return the favor! Thanks again!

you'll need a conversion u joint and conversion uppers. As for backspacing JBrue can help you out cause he is running the 68-72 version. I have a 67 A body rear. When you get the rear end if it's an Eaton posi you should check the 2 pinion thrust washers. There was a service bulletin put out on them cause the brass thrust washers wore out prematurely and they were replace with a different alloy thrust washer. Mine still had the brass washers and they were paper thin.

Thanks for the info I am going to have the rear completely rebuilt and plan on running a Detroit locker or a new eaton posi unit. Do you know what conversion U-joint I would need? Thanks again for the help!! I am going to buy the kit from UMI for the conversion to an A body 10 bolt.

for the conversion u-joint.... NAPA part number: 240-0447

I upgraded the straps to girdles as well.....I lost a cap at 80 mph and it that sure woke me up....
