Where do I go for the headliner and front windshield post vinyl? I know that they have the kits but where do I buy blue vinyl. I need about 4 yards of this stuff to cut out my headliner and post covers.

I don't know about the pillar vinyl because I simply dyed mine but you can get a pre-cut headliner with the foam already attached from http://www.datsunrestore.com/catalog.html for $54.95 in a variety of colors including the OEM blue.

Any qualified trimmer should be able to match your specifications. I have always used vinyl dye myself with excellent results that have lasted 8 years and counting.

I am replacing the vinyl pieces in my '71 Z. As long as I am buying vinyl, why not get the correct color? I have the patterns. I just need the vinyl, the 1/2" sponge rubber and some correct glue. I guess I can go to a place here locally but they will have to order the vinyl. Where do I ORDER the vinyl?
