I agree with Jason. I have a similar set for my 68A Cabriolet. They attach to the wooden header for the top and receive the pins which are part of the frame over the windshield. The two wing screws secure the parts to the pins. Gar Williams
Thanks Guys ...................... I have a fellow who really needs them for his 68-A "A" Cabriolet, so I guess that is what they are for. Thanks again, MIKE
