We are all familiar with the problems of getting aftermarket Roofrail weatherstrips to fit properly. Problem can be overcome with some quality GM originals. I've been sitting on a pair of genuine GM weatherstrips and no longer need them. Part #9878788 (RH) & 9878789 (LH) for '73-'77 Chevelle/Malibu/Laguna. Also for specific model Century/Regals, Cutlass & LeMans/Can Am. Can provide crossover for those vehicles if needed. In original boxes.
Price: $115/ea; plus shipping (The Parts Place wants $595/pr...lol).
