[72 Cheyenne402]

I have the same problem at first it was devistating. (My truck is from Houston and salt gets in everything down there.) I found a 71 AC cab for a replacement. it is in a lot better shape. My 72 cab is rusting so bad around the windshield pull the rubber back a little and the rust falls out aroud the seal. I hated replacing it but it seemed to be the only logical desision.
