Hello, I am going through the interior in my 65 this winter. The existing door panels have a 5-1/4 sreaker grill into the panel that looks factory, but it is not. I want to keep the speakers, so I would like to do the same. The grills are not the grill that comes with a speaker. It's a mesh that is glued on the inside and the cutout does not show the board material, The vinyl is wrapped to the rear of the panel. How is this done? I e-mailed a couple of custom interior shops but received no reply. Does anyone have ideas.
