We have a member who is restoring a 4 door. He wants to know the type and size of screw needed to attach the firewall to the body. He does not have internet access so if you can possibly help him, send me a message and I will put you in contact with him.
Dennis, i used 3/8" X 1" carriage bolts in my 24 Fordor, i also put a thin bead of caulk on the firewall before i pulled it together as the metal to metal is not a good fit, the felt strip at the top ill compress enough to keep water from running down inside.
5/16" carriage bolts are what the steering column flange takes and I think the '24 tudor I did a couple years ago also took those same bolts for the firewall to cowl. Not sure if the fordor is the same or not. Also put a bead of caulk across where that felt strip used to be. It keeps the coil box from getting wet.
I'll go along with Adam. I don't think a Fordor is any different than any other T that year. Without going to the garage, as I recall the 5/16 carriage bolt goes in from the inside of the firewall through the frame bracket, and is attached with hex nuts, raven finished.
I used black Dum-Dum!
Sounds like a good application for asphalted bituminous roofing tar.
I think that is what Dum-Dum is! (or close to it)
I have never seen any bolts in the fire wall brackets other than 5/16.
Thank you everyone. I will get the information to our member.
