I am in the process of replacing the entire floor pan in my '68 convertible. I have the full pan and seat pans but I need all of the floor pan supports and toe kick/firewall (floor pan to firewall ). Any suggestions on the best manufacturer of these parts(Dyncorn, Goodmark, Keystone, Autometal Direct, other) and a supplier that specializes in body metal that would cary all of the parts(I have found sources that have some but not all of the parts so I would end up ordering from 2-3 suppliers). Thanks for your help
