My understanding about the Crestline model had to do with Ford not having a hardtop two door model like GM started offering with the '49 year model cars and Chevrolet in particular. They were even supposed to have been offered in the early '51 model production and I have seen as many '51's as I have seen '50's. My only experience with the side moldings was to see them on an actual car and as I recall they were a thin chrome plated metal molding and the method usually used at the time would have been a clip on the back of the molding that attached to a hole in the body. The interior also had several trim differences including a different steering wheel and upholstery as well as additional chrome trim on the dash. There're several for sale on E-Bay and it would be easy for someone wanting additional information to look for the pictures there. My understanding also is that they were only offered in three colors, Bronze, Maroon, or a Yellow and Black was always the secondary color.
