The first place to look/read is the HAMB - www.jalopyjournal.com/forums.

That site is devoted to traditional hot rodding.

On another note, tell your friend he actually needs a '32 wishbone for that project. The '33-34 is 2 1/2" shorter. Mike Bishop hisself will tell you that his book is incorrect. It is a misprint, and the publisher has refused to change it in recent editions.

Bishop posts on the HAMB daily, his username is AV8.

They have a nice For Sale / Wanted section there. Post a want ad for a K-member and you'll have one by the end of the day. $300 -500 is the current going rate.

Good luck.
