Thread: firewall replace welding question

Tweet

Ok guys I am installing a new bitchen firewall in a 34 fordor have a question regarding instructions on welding. In instructions it says carefully grind the edge of the cowl smooth, Are the talking about taking the lip that that comes over the firewall part of cowl grinding it down to be smooth with firewall. orignal way henry did it was the lip covered firewall and was only welded in a few spots in corners. ok next thing in instructions says take your time weld the edge of cowl as indicated looks like in picture they are welding right on the edge that was removed. I can't understand why you would remove this lip unless just to make a smoother aperance I like the way henry
did it. What did you guys do just weld spot welds we removed to get old firewall out and that's it or weld under lip also. And if so just here and there
or all the way around. Just a little confused don't want to mess up. I am including picture of new firewall just sitting in car not pushed in yet took a while to get old one out.
