@Ron H , that was me that sent you the various seals and windlace. As I reported back with the initial purchase, the windlace was a hit or miss product. One box would come in fairly accurate and another box may be too large, too dense or too stiff. Then to make matters worse, I have had guys order the seals and install them and say they fit well. So for whatever reason, some of the cars were not as tight as others.
As for as reproducing the part correctly, a lots of time, it is a matter of finding something that is very close and adapting it to situation. I know that the current reproduction piece is purchased in the raw form and then sent out to a second vendor who applies the cloth covering.
Like anything, it comes down to cost and what is the economical balance between doing the part from saying being 80% correct to being 95% correct for the manufacturer. I wish that there was a better solution. But even the 66 and later models who uses just a rubber extrusion without the cloth covering experience issues with those seals. The factory original parts have always been a better fitting part.
