B80 Drip Rail Molding?

[davischevy]

In another thread, B80 Drip Rail Molding became the topic.

I have a GM "Chassis and Body Parts Catalog" for Chevrolet Trucks 1946-72 Dated May, 1979. I ordered the parts book through the local Chevy dealer in about 1981. In the RPO section, page 69, no RPO B80 Drip Rail Molding is listed.

I don't have an assembly manual, or A GMC parts book. Years ago I had a friend with a 1967/72 GMC with drip rail molding at the time he said it was a GMC option. leddzepp says jeremiahking has an original 1969 GMC with the RPO B80Drip Rail Molding listed on the s.p.i.d..

I'm wondering now if the option was a GMC RPO.

I'm sure somebody has info on this. Please take it from here.
