I own a 73 and of course can only find up to 72 year for the seal, anybody have one in good condition or know where I can get one, can I make a 72 fit? The one I have has a few cracks and a piece broken out any way to refurbish it?

There is a company that makes plastic ones for some cars. I bought the plastic type for the rear bumper filler on my '74 Malibu. I just looked for the literature on it, but must have tossed it. Maybe a Google search would find a place that makes them.

Hope this helps........
