Bed is a lil different, like height, slope and 1" I think. Who knows, maybe U can put on there and Fred Flintstone it, LOL. Get U a friend and set it on there and see if U can cannibalize, wateva to make it work. Worst it can do is not fit and U just sell it and get another one. Just my INANE sense of humor BOIRD opinion.
OP: U gonna have to look also and find the longer Bed length on the DT 1500 trucks. The popular size is the shorter 5' 7", not the 6' 4" that you have the top for. You might have to go for a Quad Cab for the longer bed vs Crew Cab, you gonna have to shop around.
