Greetings, all. First post here at SRS. Looks like there's plenty of experience on this board - I'm a beginner, myself, and I was hoping to solicit a little feedback / advice from all of you.

I'm toying with the idea of a gear swap on my '67 Chevelle. I'm still in 'planning mode', and someone pointed out to me yesterday that maybe I should install a limited slip differential while I'm at it.

Interestingly enough, I found out this morning that a friend of mine has a complete 10-bolt sitting in his back yard. He doesn't know much about it, except that it's supposed to be a Positraction unit that came out of a Camaro (year unknown).

I can probably take it home for a song, so I think I'll go have a look next week. Experiences with this? Do I just measure end to end to find out whether or not it'll fit? What else should I be looking for? I wouldn't know what a limited slip differential looked like if it bit me in the a**, much less who built it (e.g., Eaton, Auburn, Dana, etc.). All I can think to look for is:

- Casting numbers (he didn't see any, so...)
- Determine gear ratio (be nice if they were 3.73s :o])
- Check that the gears look 'okay' (no rust, scoring, etc.)
- Verify Positraction by checking that both ends spin the same direction


TIA,

The Camaro rear will not be a bolt in. The housing is completely different, leaf springs vs. coil springs. The differential unit itself should interchange as long as it is a first or second generation Camaro. I have never met anyone who can change the gears from wone case to another and not have them howl. You always have to use new gears with a 10 or 12 bolt. Hope this helps

If ya ain't drivin' it, it's just junk in the garage...

Welcome aboard Bill. Glad to have you here. Lots of knowledgeable and friendly folks here. Take Patrick up on his offer of help, he's a great guy. There's also another guy in your area on this board that's a trans guru, if you happen to need any help in that arena. Again, welcome to SRS. :)

Thanks for your replies, the warm welcome, and especially for the offer to help!

I don't know yet whether I'm going to try this myself or not. Most of the people I've spoken to say I oughtta job it out. Like I said, I'm a bit of a newbie here, and this is supposed to be a real bear of a job. Although I think I just found out where I can borrow the tools I'd need...

In any case, I haven't had the opportunity to see the unit yet. If I'm understanding correctly, the entire thing is useless to me (including the posi carrier - did I say that right?) unless I find that it's all encased in an 8.2" housing.
