I was going to order pinchweld moldings for my 66. I noticed that there are two different styles, open end and a closed end. Can anybody tell me the reason for the two different styles and what determines which to use. Any help will be greatly appreciated. :confused:

There really should only be one style, "closed".
Some of the other GM A-body convertibles have additional trim that meets up with the pinch weld molding that goes around the back, (Pontiac and Buick)

THANKS !!!!! Todd
