Ok, I know this won't be a thread burner but, can I see your firewalls? I'm having a **** of a time doing mine for my 53 Stude. I just can't get it to look right. I know it's just a fire wall but, it's mine and I want to be happy with it. I set the engine back and I'm running a vertex mag . The mag actually sits under the cowl. Any pics or ideas would be appreciated. I'm using 19 gauge cold rolled. The top of the fire wall is to be welded to the car and the lower 2/3 will be riveted to the top and to the floor. I have a full roll cage in the car and want to keep the body removeable. I'll get some pics up tomorrow of it laid out in cardboard. I'm just not happy with what I have.
OK, I'll bite. If you have a full roll cage, and the body will be removable, then I take it the floor must be welded to the ch***is and be riveted or attached by some other removable method to the body? If that be the case, why not just weld the firewall to the cage and the floor pan? Then you can have the top ledge of the firewall solidly welded to the cage and the body can sit on the ledge and be screwed or bolted to the ledge? You can do the same thing at the rockers and door posts. You can cut your floor pan just behind the cage and attach the wheel wells and rear floor to the car body shell and then you could undo a few bolts and lift off the body, leaving the ch***is, cage, firewall and dash ledge. Whatever you do, I'd use bolts or screws with thread inserts instead of rivets. If your really wanting to be able to remove the body at some point in time, you have to build some structure into the body shell or it will get ugly if you ever pull it off and expect it to go back on.

This is my firewall I made for my 35. http://www.roddingroundtable.com/tech/articles/firewall1.html Do a search on here. There was quite a few posts about this same subject.
Bear with me just a sec. This may sound stupid but I read an article awhile back where a fellow took one of those small, shallow steel wheelbarrows, cut one end off, placed that end down and then cut out the appropriate area to fit and welded it into place. Sounds dumb but once painted it looked pretty slick. Cost about thirty five bucks.
