These numbers were only used on the Regals. Here are the numbers for a MonteCarloSS. The only difference is the pattern embossed on the molding.

Each model of G-body has it's own set of B-pillar moldings.Even on the bright moldings. The only difference was the pattern embossed on them. Buick and Chevy were the only ones that used the black moldings. The one odd ball out of this bunch was the 1986 Pontiac Grand Prix 2+2. It used the MCSS moldings.
