Alfaguy:
I ordered a sample of the same gasket to use on my 72 and it is/was too shallow. Pic 1 below (from left to right) shows
gasket for 1/8" glass (VTS-477), original 3/16" gasket, and the 3/16" gasket ordered from CRLaurence. The new 3/16" gasket is too shallow.
After endless searching online and visiting multiple glass shops, I decided to shave the side "ribs" of the 1/8" gasket to use and it has worked flawlessly.
pic 2 is a shot of the trimmed gasket fitting into the channel.
pic 3 is the gasket in the frame during assembly. This was the rectangular front window, so the corners are (welded)melted together.
pic4 is a shot of my "jig" used to trim the gasket.
