I am working on the interior of my 51 2 Ton and would like to find the correct boots for the shifter and parking brake. When I pulled up the Trans cover I found that the shifter had a very think Gasket around the base that looks like it may have had a rubber boot at one point. The Emergency Brake had a metal bracket rattling around. Is there a source for these? I cannot seem to find any documentation about the differences in the 2 ton cab interior from the 1/2 ton.
