I was mounting the body accordinng to the where crowl bar mounted to the frame (mounting holes where already in the frame).
This lead to the firewall (when pushed up tight to the crowl bar) with a 1/2 inch to 1 inch gap between the front of the firewall and the frame.

Should the firewall be pushed tight against the front of the frame, then push the crowl bar tight against the firewall and tap new mounting holes??
OR
Do I stick with the where the crowl bar originally mounted to the frame?
