    Crewcab LWB to SWB conversion

    Kleedus, Yes, I've seem several 3/4 2wd crews also. No cab lights, single rear wheels. My 3/4 frame measured a full 8" in height, and .250" nominal thickness. 1/2 ton is 6-1/2" in height, with a .180" nominal thickness. (at least behind cab, where I grafted the two together) I'm surprised...

    Crewcab LWB to SWB conversion

    Update: Front end conversion 3/4 to 1/2 (2wd) I was hoping to just swap ball joints and install the 1/2 ton spindles. I know the stems are different. Research on ball joint sizing came up empty. So, I tore it down, looks like the 3/4 lower A arms have a larger diameter mounting hole for the...

    Every chance I get. Kind of slowing down now, getting around to building the CCSB I've wanted for years. Been saving parts and pieces for a long time. Thanks for the welcome. And yes we used to run some of the KOTS events in Tx, Ok, NM, and Az.

    Crewcab LWB to SWB conversion

    lol, yes, went much easier than anticipated. Measure twice, cut once. I tried to have everything ready. TIG'd the joint, root, filler and cap in ER70S, went very nice. Fishplate rear plate and boxing interior of frame with MIG. The time includes swapping fuel tanks, and fuel and brake...
