I've been told 81'-93' doors will fit (I got a 92' w250) but the 81'-86' interior panels do not. Are the mounts still their to swap in my good 92' interior panels or must I jerry rig it?Also told the 81' - 93' beds will all swap but the 3/4 tons have a series of mounting tabs to light the beds up higher. If I acquired a cheap straight 1/2 bed to work with how much work and how many am I looking at to fab lifting tabs that are strong (previous owner used to carry like 4-8ton concrete slabs in the bed). Could I just fab some blocks/hockey pucks up all around, kinda like in those shitty body kits? i have a high powered stick welder on hand and more time then money.Thanks guys.

Not to sure about what year fits what, but i can tell you my box has 4 spacer tabs only on the front half of the box portion by the cab. They look to be about 2"x2"x6" not very thick maybe 1/8" (i'll grab the tape once the rain stops) and i can't see why you couldn't drop a 1/2T bed on it, hell I'm almost done putting a 05 GMC sierra 1500 cab on my 92' W250 fits like a glove if you got enough time to help it along ;)
