I insulated the floor of my ‘54 3100 today. (It should be noted that my truck has a replacement repro floor.)
I wondered how to deal with the brake cylinder access.
Given the fact that the access hold is only about 2” in diameter I really don’t think I can remove and replace the cylinder top and retaining clip through it, so I’m thinking I’m going to have to perform that maintenance from underneath the truck.
Is my 2” access hole typical of the original? Do you 3100 guys usually work through the floor, or is it pretty common to go underneath?
I sure wish that master cylinder was on the firewall!
