Good lookin car. I've been researching about this because I have 1963 Pontiac Tempest too and I came across your forum. I have been trying to learn about them because I bought mine for $300.00 and it was in great condition. As soon as I can figure out how to upload some pictures I will send you some of mine.

I hope you continue to post pics of this rebuild as they happen.  I'm looking forward to seeing the finished product.
