Yeah, I've been lucky so far. The vent window pair I purchased the other day was great!
I'm not sure if these, like most other weatherstrips I've purchased, have the molded in numbers somewhere. I'll have to look at the parts car rubber.
I would prefer these in the original, unopened Ford wrapper.
I'm only missing two other weatherstrips (back window and driver's side fastback roof) to have all original NOS rubber. I'll do a separate request for those.
