My 61 is a fletside shortbed and I love the look of it. I lose a little bit of workability due to the shorter bed, but I think it looks great. I am going to keep the six in mine, but I am gonna drop the back about 2 inches, the front is already dropped. I think that they look really cool with a slight drop and nice rims. I am going for a slightly custom but still origional look. Kind of like it might have looked when it was a young truck. Anyway...short/fleet is my preference. But if I had to do a lot of work with the truck I would want a long/fleet.
