Thanks, John.
The frame is completely bolted together. Crossmembers are extruded aluminum. Crossmember gusset's are forged or cast aluminum. All fasteners are metric, 10.2.
Frame rails are straight, C-channel, heat treated, mine are .375", single channel. I don't remember the tech., specs. They put warning stickers on new frame rails, prohibiting, welding or drilling frame flanges. The only welding on mine is at the rear, where the factory cut a pie-shape out, and bent the top flange down to form the rear taper. The flange is partly trimmed away, beside the engine for clearance.
I've seen guys re-rail a truck, by unbolting everything and using many, bottle jacks, and blocking. Then, slide the rail all the way out the rear. New frame rails can be ordered, pre-drilled from the OEM. I have changed out the frame horns, at the front, myself, on a truck I once owned. That was quite a job, with bumper, hood, spring mount, rad. x-member, forward engine mount, all attached.
It is really simple in design. Just everything is super heavy.
My handle... OK. I don't really use the CB, much, any more. Back when I started, in the 1970s, everybody had to have a handle. I started running coal, with 4 other guys, 5 trucks in a pack. After so long of the guys not knowing what to call me, they told me if I didn't come up with my own handle, they would make something up. Fearing what they would come up with, I brainstormed and decided on "Flywheel". I thought it was cool, you know, engine part, but, also, fast truck...left lane...flying wheels.
It took about half a day for them to shorten it to "wheelie"... then further to "Willie". I think only three guys still call me by that, today.
From this...
To this...
And finally, ...
I guess that is OK. I always liked Willie... And Waylon.
