Cool build! My little brother has been building one also. He started out with a mostly rustfree slant 6 71 New Mexico car and we found a 1970 Duster 340 car for parts. After we sold a lot of the parts that we werent going to use off of the duster his drivetrain was pretty much free. Here is a pic from a few years ago:


While you have the body off, you should consider sub frames connectors if you havent done so already. Here is a shot of his before the underside got painted:


Good luck with your project! Take alot of pics and keep us posted!
