Outer Limits 4x4 Board

how much and how hard is it to swap a gen 2 xtra cab body with a gen 3 xtra cab body? and wat sort of prices and shit should i expect... the old man keeps suggestin i should, and i dont mind hte idea... a lil info would be nice though!

engineering information would be helpful 2!

thx

dunno bout x-tra to x-tra, but i've got a gen 3 single cab laying in my back yard, which i was thinking for all of 2minutes of putting on my gen 2 x-tra cab rig, and it looked as tho the mounts were extremely close,

thats as far as i got tho, i got side tracked..............but it looked close
