I'm finding conflicting information on the internet, but someone here surely knows.

Thank you!

The Summit style are the correct 71 style

Scott that is so sanitary I think I wouldn't finish it. Just drive it around like that!!!!!!

Thank you Scott!

I'm getting ready to do the dreaded side door glass installation, once that is done things are going to move pretty quickly.
