I had a little time this weekend (basically my *ss was draggin on Sunday because of the record heat on Saturday) that I decided to take some more photos , measurements and do a comparison of run channel materials on G-Body, specifically, OE Malibu run channel and Caprice. I thought I'd resurrect this thread with the hopes someone has an "in" with one of the companies that could make this stuff happen.
My opinion, I don’t think you can do better than the 1720 for the short side and top piece of the window. For all practical purposes it’s an exact match to the factory material.
On the other hand, the 1336 leaves a lot to be desired.

Again, my opinion, the 1395 is closer to the shape of the OE material but according to the dimensions, the 1336 is ½ inch high and the 1395 is 35/64 or a difference of 5/64 in height. Does that make a difference, I don’t know yet.

This is the material used on the Short Side and Top of the Caprice run channel. It's nothing like anything I've even found in the catalog.

So, what does all that mean? In my opinion it means we're good as far as a perfect match for material on the short side and top. It also means however that we need to keep looking for a more suitable replacement for the long side and specifically a better option than the 1336. This is really stupid, I can buy front and rear run channel for just about any year four door Caprice but not for a G-Body. Do not get that at all.
