Dave, I'm glad you like the videos, sort of takes some of the mystery out of some of the work, even if you paid somebody to do it you now know whats going on at least. On my sedans top wood its put in with black RTV silicone on the roof, I read somewhere thats the ticket for expansion and so far its worked well and you couldn't yank the wood down as it bonded to the fiberglass inside well. My buddy had a great 'glass pickup the upholstery shop fiberglassed a 2' x 2' piece of plywood to the roof to mount the overhead console, naturally it buckled the roof, which was noticed the first sunny day when the car was done (at the NSRA Mid America show!)
It took me several months to completely do my cars interior (nights & weekends) and like I mentioned I was a professional woodworker for 21 years, but there is alot of woodwork involved. Gives a fella new respect for their trade, but after the wood was installed on my headliner it really was quite easy after watching the videos as I really worried about that part. Best of luck Matthyj
