    Also looking for misc t-case parts:

    tcase mounts
    Shifter base etc (I've got a shifter)
    Drive shafts
    Top shift tcase (if the price is right such that I can build my own doubler)

    Side shift case is easy to convert for $0 if you cant find a top shift.

    I'm running the RA Design unit and like it a lot, daves look nice too but always seems to be out of stock. FWIW, the only reason im running it is for my 3rd case, the shifters would be way to far back without it.

    For dual cases just twin stick it, not worth the $$ and better off putting toward otjer things.

    Well, it was a great day to be out under the truck doing some pre-wheeling trip looking around. While I knew it was probably time, I've created a project with too little time to complete.

    So this is what I noticed:

    So I got to drawing

    And damn, plasma cutters kick ass

    And stopped here. Trying to decide if I should wrap it around the sides. The end result should gain me at least a few inches more than how it was mounted before.

    Yep. Got a lot of stuff to get done before the March ride - doubler install, modify tcase crossmember, driveshafts, finish rear bumper, add springs to front spring pack, and diff guards.

    What about twin sticks for the dual cases?

    That's on the to-do list as well - those arrived in the mail this week as well. Hopefully that'll be an easy item to cross off.

    Made a little progress today. Just got to figure out how to mark and drill the holes for the rear tcase mount.

    Hoping that my addition to the crossmember holds up. It's 1/4 inch but there's not a great way to reinforce the butt weld without hanging a bunch of metal off the bottom which I don't want to do. I tried to add a couple of metal coupons across the joint to help - we'll see.

    Could you add a 1" +/- vertical rib along each side, basically under the tall part of the mounts? Welded perpendicular to the flat plate. Did you bevel both sides to get a good penetration weld on it. I mean typically the weld is stronger than the base material, but having that extra weight hanging off could bend even a solid piece of plate. Adding even a single rib will dramatically increase the overall strength of the crewmember.

    That's a good idea. I beveled the joint but I'm also worried about the weight. I'll get the tcases mocked up and see where I can add some bracing.

    Here's how it finished up. Used some 1" square tube to brace. It's not very symmetric but it should do the job.

    Well this is probably why I had vibrations at ~ 40 mph.

    IMG_2414.JPG

    So I cut the yoke at the weld and then 6" out of the driveshaft to fit with the duals.

    IMG_2415.JPG

    It was a good tight fit back in the tube and then welded. Do you think it'll hold up? It won't see speeds > 40 mph and primarily trails.

    If you were looking for road gear I would probably see about having it balanced and make sure the joints were in phase, but just for bumming around from trail to trail, I'd say you will be fine.

    This may be the set of mods that finally gets it off the road. Still have to deal with Windrock though.

    Thanks. The joints are in phase but it ain't getting balanced :hillbilly:.
