67-68 Custom Trim Interior photos/info needed

[Overdrive]

I'm looking for some photos of original '67-68 Chevy and GMC trucks with the Custom package (cloth and vinyl bench seat, vinyl door panels, etc).

I've got a '67 GMC 910 with the plain vinyl seat interior and want to upgrade to the Custom interior. I'm trying to find what I need to change to get the proper look. I already have the fancy GMC horn button, and I imagine for the rest of the package, I need to redo my seat in the original cloth and vinyl. What are the original Custom door panels made with? padded vinyl over the steel panel or some fiber board backing? My truck is dark green, with the metallic medium green interior. I have received material samples from SMS, and they provided two choices for the cloth. Where would one find a pattern to do the seat upholstery? Could someone maybe measure the dimensions of the cloth inserts and location?
