Precision Gasket and 67 Mylar strip

Thanks Dar, I will into the 80's Chev truck stuff. This is for dads fastback. As far as I know/knew the Mylar lockstrip was the same for all 67's whether front or rear??
Why dont they sell it for fb rear?? Its the same as the front.
I thought cuda vert front ws gaskets were the same from 67-9??

If its not a convertible, Steve, you can use the stuff for 80's GM pickups, I think. Pretty much any windshield shop should have it. Convertibles use the special (read:SPENDY) lockstrip
