94 crew cab on 81 frame
 

Ok here's the story I bought an 81 c30 crewcab dually with thoughts it only needed rockes and floor pan well I was wrong. Might as well find a new cab. In my searching I found a 94 crew cab on a custom built frame well I bought it and know I'm thinking about setting it on my 81 frame which I only want to do if it will set as low as otherone did cause it is lowered 6 front and 7 back or I could be back wards how much different will it sit. I know I have to built new mounts but will it sit as low with out haven to cut floor thanks in advance
