firewall pinch weld
On the 66 C 20 I'm working on there are 2 places on upper firewall pinch weld that the pinch weld is crimped over. Its pretty equally spaced side to side and I'm trying to determine whether factory or previous owner.

Re: firewall pinch weld
Pretty small pictures but that lip should be flat on top or upside down L shaped . Looks like it was bent down. It should be consistent all the way across
