Wow in the first shot with the old firewall, the frame fits just like mine. Tight on the pass side and wide on the driver. Well at least it appears to be a "standard deviation". Maybe someone will have successfully pulled off a re-center without cutting out the dash and firewall! The clamps are off the same as the frame. It looks like if the frame would line up so would the clamps.

gmwillys has me straight on the seats. I now have that figured out. I am hoping for some pics from him on the windshield. He was thinking the mounts might be backwards. This could be a tough one.

Man that CJ of yours is coming along! I can't wait to see the finished project. You are definitely good with the metal work TJ!
