Re: Getting to the pinch weld?

What I described is often referred to as a stock floor body drop, and the one nearly every home guy does on this series of trucks. Plus what aftermarket frames effectively due.

The CK series past 73 do not lend them selves to a traditional body drop like let's say a 50's truck.

You still need to measure it to find out how much to remove. Then cut your body by that amount to remove a lets say a 3" strip of metal from both the fire wall, and back of cab. You just cut the floor off along the rocker panels about a inch in from where the door sits fully closed. Them you square everything back up, and weld it shut. Make filler panels for the door edge or step as it would be then. Then you do the same to the bed to match. The CK series beds in bolt, and I would consider working on it in pieces. Then tack weld back quickly, and reassemble to verify everything is still true. Make a filler panel for the back of the bed. Construct drop brackets for the front, and rear bumpers. Section the same amount as previously out of the core support so the front sheet metal drops down. Cut you column down at the slip joint, and put in 2 universal joints to reconnect it to the steering box. Modify your bench seat or buckets to lower them to match. Or as some do fabricate most of the floor pan to make seat installs easier. Tweak the break lines to allow for the body drop. Most of the wiring should be easy enough to zip tie up, and gives a couple more inches of play for a nice routing job. For the heater/AC depending on level of trim you have. You have to cut around the lower end of the box or go to a aftermarket system. Most due aftermarket if they have ac since the tires now have a tendency to hit the box. You either need use slosh tubs, trailer fenders, and or expensive surgery to fix you factory wheel wells. Or just toss them if your not planning to drive in the rain.

Now you may think I am a old idiot, and want to channel your body to show me up. Which is the third way it can be done. This usually looks like a abortion, and the channel is stupidly annoying to work around for cab interior fitment.
