Two-door sedan windlace
For those who may be interested:
Here's the black Fairchild offering sold in 16' lengths by RockAuto for $13 (and other vendors for five times that) compared to the OE blue windlace/weathercord/welt on my '69 Valiant. The grain is significantly different, but it's better than the eBay stuff. It's a '68 Valiant daily, so close enough for the girls I divorce:
Problem solved, case closed, and everybody's assistance is greatly appreciated!
