I currently have a late 70's C60 tow truck. I'm wanting to stretch the frame to accomidate a 1980 crew cab and regular bed which i also have.I've done ALOT of measuring and it appears that if scrap the tow body a regular bed will fit nicely.I'm kinda unclear on how to measure the crew cab for the correct lengthening of the frame. I've never attempted a frame stetch before and I'm a little intimidated by it.After I've completed the stretch I would like to add 2 1/2 ton rockwell axles.I have access to these axles but before I purchase them I would like a little input from anybody that may know a little more about them. If somebody could give some PRO'S and CONS or DO'S and DONT'S it would be greatly appreciated.

<font color=green>Rather than stretching the body I'd suggest shortening the bed. Put the crew cab on there with a short little bed, the cab would probably end just a bit before the rear wheels, take about 2 feet or so out of the bed and add it on. Frame stretching is not to be taken lightly, the last thing you want is for the truck to break in half on the freeway... I always wanted to put a crew cab on a short frame though, it would be pretty cool.
