I just finished installing the upper trim on my 65 fastback's dash pad. Thats when I noticed I am missing the bottom metal trim that holds it down. Is there any way to do this without that trim? I tried holding it down with screws, but it strips the dash pad. It wont hold all the stress. Right now the dash pad looks horrible and it bends up on each corner, and bulges out. Any suggestions? PLEASE! Thanks in advance!!
