Robert..I'm pretty sure the coupes & 2 dr sedans used the same door. All the 39 GM cars of that year, Buick, Pontiac & Olds were very similar so if you see one on them available take a bunch of measurments and check em out. Lets us know how you make out...[P
as far as i know the sheetmetal on the cars /trucks look the same from a distance but are different and dont interchange.im building a 38 pu and even though the car/truck look similar they are different,even the grill is different
