I am restoring the hardtop for my Triumph TR3A and would appreciate some input. I bought the headliner fabric from The Roadster Factory. However, my hardtop does not have the original listing rail. does anyone know what it is made of and its dimensions? Also, if anyone has photos of the finished headliner/gasket installation/rails and any other details that may assist me in reinstalling my complete hardtop restoration I could sure use the help.
