A local upholsterer told me he would not install a custon headliner in a 66 mustang because any thing other than original material would be to heavy to stay put. Anyone have a custon headliner and for how long.
he's right. the only thing holding up the headliner are a few thin metal archs and the windshield and rear window. the headliner doesn't actually attach to the roof. you could weld in supports for a custom headliner or glue the headliner directly to the roof.
fiction, custom headliners are made for all kinds of cars, including mustangs and falcons, everyday. the easy way to do it is to glue some foam blocks to the roof of the car, and shape them as needed. then glue some thin foam padding to the foam blocks, and glue the headliner material you want to use to that. he either doesnt know how, or doesnt want to do the job, and didnt want to quote you a huge price cause you might actually accept it.
Well, if you attach anything to the inner roof, prep and paint it beforehand. I have a friend that has a Fairlane that someone used expanding foam on the inside of the quarter panel to do some custom trunk work and the foam allowed water to get between it and the metal and it rusted from the inside out.
My headliners out in my '65 and I don't believe there is any primer or paint under the roof except where the bows attach.
i was going to do a custom headliner when I was redoing my 67. the problem was that alot of the custom headliners weren't that good. the radius turns in the corners weren't smooth. this was on of my main concerns. I would have had to pay too much for a quality custom headliner. to get it done right.
if you look at all custom liners now. they all glue to board that is then mounted to the roof via screws/glue into the metal ribs or wood screwed to these ribs.
again, the radius turns in the corners are where the quality shows. wasn't worth the extra $$$ to me. went with the stock liner and it looks great!
