My glass guy ordered a gasket for a 69 Barracuda using the NAGS number and measurements of the opening from Precision Rubber Products. It was $249 bucks but was correct, fit perfectly, lock strip included and looks great.
So, tommorrow i'll get with Year One and try to get my money back ($159 + shipping to Canada) for what is, obviously the wrong rear glass gasket for a 1969 Barracuda Notchback Hardtop. I'll let you know how i make out.
