Does anyone know of a site that may help me figure out how to convert a long bed to a short bed? Thanks!

From GMC Paul
"Take 12" out between the front and rear cab mount, this moves the rearend forward and the crossmember that the trailing arms are attached to without changing any distances so no need to have rear driveshaft shortened only the front shaft needs shortened, then remove the front frame to bed mount and and take and move your rear cab mounts back 12", cut your 8" off rear of frame and you have a swb frame. Besides replacing the brake lines with SWB ones you will also need to change your parking brake intermediate cable, swap out your rear taillight intermediate harness for a SWB one or make a loop in it to shorten it up some. Thats it other than the welding that needs done. "
