Okay, here is my project. 78 with t-tops nothing special. original 400 engine, car needs total restore.
floor pans were shot
pulled engine and verified numbers matching
replaced floor pans what a pain in the a$$
sprayed Lizard Skin sound deadener to seal up and finally finish the floor project. pretty happy with the results, it actually dries black color.
have more photos to show, too tired to continue tonight.
