Okay, I give up. I spent big money on ebay to purchase what I thought were correct NOS Door Weatherstrip for my 71 Z28 and they do not fit. The Group and part numbers are correct on the boxes, GR10.694 1#9868430 and 1#9868431, the W/S look exactly like originals (and the re-pop's I have), but they are approx. 6" too short and the little plastic pins that push into the door do not align with the holes in the doors. The first couple pins on each end align but the rest of them have an entirely different configuration. The ends fit and align perfectly with the screw holes. These do have some numbers embossed on each end but I don't know what they mean. These numers are LH front 8291, rear 9383 and RH front 8290, rear 9382. Does anyone know what these things fit, they do not fit a Camaro door? Has anyone ever run across this issue? Here are some pics to help with the story. So I assume somewhere along the line, way back when, some parts guy at a GM dealer was taking the Camaro W/S out of the boxes and replacing them with these; then selling the Camaro stuff. I am currently working with the Ebay seller on getting this deal undone, but I am curious if anyone has had this problem before or if anyone knows what these fit. I also want to make this issue known to those of you who are buying NOS GM weather strip, apparently the numbers on the box don't mean much.
