Is there anything a person can do to "posi" a 10 bolt rear (or at least upgrade)? I read the other post on this topic but no one covered that point. I could not hook up very good with my old engine, and with a new and more powerful engine on the way, am worried the problems my be worse. I don't have $ for a 12 bolt. Thanks.

Yes you can beef up a 10-bolt. I decided to keep my 8.2 10-bolt in my 67 and had it rebuilt with an Eaton limited slip, new Richmond 3:08 gears, a set of Superior axles and a rebuild kits with new bearings, seals, etc. Got all the parts from Drive Train Direct.

It wasn't cheap, and I probably could have lived with my old axles, but then I tend to have the "while the patient is opened up....might as well do it all".

I also opted to have a rear end shop do the work.

Check out the Eaton posi at www.eatonposi.com (http://www.eatonposi.com) . Don't mess with the Auburn units. The Eaton is best.

If you plan on putin real power to it,opt for a Corperate 10 bolt from a 71-74 Nova.It is dimensionaly the same and will bolt right in.It's almost as strong as a 12 bolt,and cheaper to boot.The only downfall,you will have to shorten the driveline about 1 & 1/2 inch.

I was going to upgrade my 8.2 to posi, but did a complete swap with a 8.5 out of a Nova for much cheaper. They wanted over $700 in parts alone to upgrade the 8.2. (gears, carrier, bearings, etc.) I got the 8.5 posi complete drum to drum for $400.

Use the search feature at the top of the page and look under "8.2 to 8.5 swap" in the engine and drivetrain section. There are several posts with lots of info. Posi is the way to go. Definite improvement!

Mine bolted right in. Didn't even have to shorten the drive shaft. There was enough leeway in the slipyoke at the tranny to make up for the 1 inch longer pinion. There is a conversion type u-joint that you have to use though.

I don't know if it will work on that rear end are not but my buddy put a mini spool in his 10 bolt chevy truck. If they make one for your rear end I would think that would be the chipest way to go.

Ditto Mark. I installed a 8.5 posi rear out of a 72 Nova. Bolted right in. I got a shorter drive line at the Junk Yard. Mine has a whine in it so I am going to put in new Richmond gears next week. I paid $500 for the rear, by the time I get the rear rebuilt I will have about $900 in it. This is compared to the $1,000 they wanted to rebuild my 8.2 and put in a posi. The only question is, could I have gotten a 12 bolt in new condition for the $900 I'll have in this one.
