Is the veneer on a 71 GTV strong enough to hold the radio on its own? When I purchased the car, it came with an uninstalled period Blaupunkt Essen. I think its from 1975, but close enough. There is a metal plate that's with it that looks like it will spread the weight of the radio along its entire face, instead of just relying on the posts. There is a threaded post at the end of radio, but it looks like I'd need to fabricate some kind of strap to utlize it.
