It's been very difficult to find information on these older cars. I know the 1941 Cadillac hearse was build on the 75 commercial frame, so it has a body length of just over 21 ft. I can't find that information for the 1952 Cadillac Hearse/Ambulance. I'm guessing it's still built on the 75 commercial frame, but I can't find the dimensions. Any help?
