My choices in order are lwb fleetside, followed by swb fleetside, then swb stepside and lastly lwb stepside. I have several '64-'66 lwb fleetside trucks. With the availability of aftermarket swb stepside bed parts and the number of years they are interchangeable, the swb stepside beds are becoming more prevalent. I like the functionality of the lwb fleetside bed, as well.
