NOS C1 Windshield Weatherstrip

[Dick G.]

I purchased an NOS C1 windshield Weatherstrip on ebay. Should this weatherstrip have the GM part number molded into it? My old NOS strips have the numbers molded into the rubber.
I thought I would try an NOS since the repos I've bought are junk. Does anyone sell a good reproduction C1 windshield weatherstrip? Manufacturers Name.
The problem is the typical wrinkling in the corners.
I have tried to work them out to the topside, won't work.
The first time I overstretched it towards the top to get rid of the wrinkles, but had TOOO much slack on top. Next!

Thanks
DG

Dick, I believe the GM service replacements may or may not have the part number stamped into rubber; some vendors did others did not. I believe I purchased the weatherstrip from Dr. Rebuild for my 1960 and it fit just fine with no wrinkling in the corners.

I looked at the original weatherstrip on ebay, but was concerned that during installation, the old rubber would not be flexible enough to stretch around the glass without breaking. I was concerned that was going to happen with the new weatherstrip, but it did not.
