I just got a quarter extention molding to put on my 68 because its missing it on the right side. The PO put bondo over the screw holes and covered them. Does anyone know if theres a diagram of where the screw holes are supposed to go?

 

Take the extension off first. There are nuts that go on from the back so this is required. Once you get it off you will see where to drill the holes.

 

how do you take it off?
