hello, i'm new on the forum. i have a '68 142s i bought in 1982 - the only car i've owned since then and still running fine. i recently replaced the rear window moulding with a nice used one. the problem is i can't get the two joining ends at the top (about 8" on each side of the clip) to seat in the seal permantly. is there a way to get the mouldings to seat correctly in the seal. thank you. steve.
