Hello. I am new to this forum. I have 2 1961 Pontiac Ventura Sport Coupes that we are getting ready to sell for my wife’s family. I have seen some info on decoding the VIN data plate. They are both very alike, but one has a paint code LCA, and one has LLA. Then both has ACC K. They both have been painted maroon, but I thought originally maybe there was a difference. Any help?
