I have an 1987 LS with bucket seats. The left rail on the drivers side rusted out at the bolt and broke. No idea why since there is not rust on the floor pan. Any idea where to get a replacement or if any other cars are comparable like an F body Firebird. The rail is beyond repair and needs replacement. The local junk yards do not have any of these cars available. When they do come in they are striped of interiors prior to hitting the yard.
