I need a good or rebuildable generator for my 60 El Camino, 283. I am not sure of the differences in them old generators. I suppose one from a truck would work. If there is a difference, let me know. Thanks.

As far as Iknow, all the 12 volt generators on the GM vehicles (car or truck) should work. :) I know on some of the cars like the impalas, and belairs had the power steering unit mounted to the backside of the generator as an option. I did a quick search on Ebay, and found a bunch up on the auction block.
Here's just a few that I found:
Auction #1 (http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=10076&item=4545447803&rd=1)

I'm no way affiliated with these sellers, just posting a few link that's selling used Ac Delco generators on Ebay. ;)
I hope this helps. :)

I have one from my 62 one ton w/283-how 'bout 25.00 plus shipping? I know it's good,I was using it until my engine ate a piston a few months ago,and it never gave me any trouble,the bearings and brushes are pretty good too. I'll send the regulator too,if I can find it. Let me know if you're interested.

25.00 plus shipping sounds good to me. Could you find out how much shipping is to 87121, Albuquerque, NM. Email me at j_chav62@hotmail.com

Thanks, jc
