Is this worth it? http://cgi.ebay.com/ebaymotors/ws/e...ndexURL=3&photoDisplayType=2#ebayphotohosting I want to put a posi in my 71 GS,it has the 8.5 one legger in it now.I had a 3:08 8.2 for it,but sold it after your helpful insight and suggestions. So would this be a good route to go or do I just find a posi carrier and gears to have installed.I'm thinking 3:08,3:23,or 3:42. Running a worked 350,TH350 shift kit and converter,planning a mildly worked455 in the near future with the same tranny.Thanks.
I kept my 8.5 and put moser heavy duty axles in, added a powertrax locker, ARP studs and TA cover. Did it all myself except for installing the new 3.42 gear. Steve :TU:
Stick with the 8.5" Same center section in GM cars and some trucks from 71-89. The 12 bolt pictured in the Ebay auction is from 68-70 Cutlass models and they are extremely expensive to rebuild and parts are almost impossible to find. The 8.5" can easily handle 500-550 hp.
HMMMMMM....Maybe this is what I need for my 70 Skylark! I hate my rear end! Wait, oh crap it's a 3:42. Too many revs for me :ball:
