Re: Firewall Prep
if you can't weld and can't pay a welder then just plug the holes with grommets or auto body hole plugs. the glue may work but if you have a firewall mounted brake unit the firewall will probably flex some and cause the glue to come off. another thing you could do is use an elevator bolt with the nut on the back side but then those will be seen from the inside. google elevator bolt for a pic. would cover a fairly good sized hole. not too proffessional looking though. some guys use them to actually weld into the holes because they are easy to hang on to and then they just cut the back side off and grind smooth. easy to make fit the hole too, if they are bigger than the hole is.
