Ok I miss understood your post. I thought you found a shop near you that was making the tops for the M35 under gubment contract and therefor they would make you a M715 top out of the same material. This is a little different issue now than what you were stating before. I know that Beachwoood has mil spec vinyl. Sounds like this guy your talking about has regular vinyl that he uses for boat covers, convertable tops etc. Just a local upholstry/canvas shop.
