Have had rear sets fitted to my cutdown.
However....does anyone know as to where I can purchase a rubber or plastic grommet to fill in where the rear brake pedal was ?
Grommets !
i just shaped a bit of alloy plate 2mm and siliconed it on 3 years on and its still there
i welded it up ,but that might not be a good idea for you though
