I have changed my bed from an 85 fleetside to an 82 stwpside. I am just getting to the stage where i am bolting this bed down, I have never had it on the truck. I just dont seem to think it is sitting right. It seems to be down in the front. there is a height differance measuring from the top of the bed to the ground. When i measeure the back and than go the the front there is an 1.5 " slope. is this normal? I have checked and re checked and I have all the supports in the correct spots so I have no clue what is wrong... or if anything is even wrong. I would just think that the rails of the bed would be levl on the sides if you where to put a level on them.
