I just purchased a 1966 Convertible, and for some reason the fella that had it before me didn't install the snaps that go on the trim, (I think) that the boot attaches to, he just used plain screws. Also, the little hooks that're supposed to hold the convertible top down are missing. I think these - http://www.mustangpartshouse.com/products.php?scid=421 are what I need, can anybody confirm? Also, what is the best online source for aftermarket parts?
