    I got one made and stopped. (The design is 22yrs old and race proven from Ryan's 3B.)

    I just remembered I don't have the axles at hand and since my "fabrication" skills are terrible at best, I'm selling out and getting aftermarket spring perches and new u-bolts. U bolt plates will be whatever I can scrape together.
    Trying to work out a deal on another F134. Hopefully it'll be a runner with some massaging.

    Threw in an order for spring perches. A rolling chassis should boost morale.
    $150 for another F134. I've got a freshly rebuilt T90/D18 and I might bite the bullet on the F134 so I don't have to buy bags of sand or concrete to set up the suspension. :shrug:

    Some YJ spring tech
    Shackle bolt 1/2
    Hanger bolt 9/16
    ~3.5-4 inch long bolt
    Rear spring shackle hangers came today. Much better than anything I could make. Waiting for the rain to stop so I can get back on the frame work.

    I tacked in the crossmember and I'm in the planning stages of where I want everything; more specifically where the axle will sit. That's why the rope and nails are hanging off the frame.
    Shackles are 6" with 1/2" tolerance for error. I feel like I'll be making the shackles again :banghead:

    We're in like sin! Courtesy of my technical advisor, I only tacked them in place. I measured here and there a few hundred times, stared, adjusted this and that and after many hours of fiddling my thumbs tacked it in place. Adjustments can be made accordingly when I have a tub and such on the frame.

    Here are the top plates. I didn't doll them up or anything yet but that's about what they're going to look like. So I made a mistake and will pay for it in welding rods and material; The square tube was 2x3 and the spring eyes are roughly 3" wide so I am going to cut off the "wings" on the spring mount plate and try to tie the other end of the spring mount to the frame (box it in).

    I extended the rear of the frame 5”. A bit more than needed but in case of errors it’s there. Hopefully in the next few weeks I’ll get some parts and pieces to get it rolling.

    Edit: I got restless and put the shackle hangers on. Eye to eye on the mounts is 44" front and rear. Rear shackles will be 4" long eye to eye same as the OE YJ pieces.

    Found these in the parts stash.

    Should work for my next suspension move.

    I would expect the front spring mounts to be more centered on the frame rails. I think the stock springs are about 27.5 inches center to center and I would think you would want maintain that dimension. Not trying to sound negative - I am looking forward to seeing this done.

    I ran mine flush on the outside like this one to retain the steering. The first thing the tires hit at full lock are the springs, and I wanted to retain what I could. The only issue is what to do with the pass side spring pad, since it will bring the spring closer to the cast housing a little bit. Noah, I can post pics of mine if you'd like to show how I resolved it. Don't know if you crossed this path yet.

    All the shackles are done and the other frame plate is drilled out.

    Springs are 45 flat and 22.5 to center pin (my measurement) OE YJ spring mounts are 44" eye to eye and that's what I'm shooting for.

    My Center pin is 1 3/4 forward of the factory bump stop iirc. I already needed a new front driveshaft. My spring perches have 3 notches so I could offset the axle to try and make up for the new location the springs will put it. They overhang to the inside of the frame maybe an inch? I'm always open to someone else taking a look to make sure I don't screw up too badly. (y)

    I haven't thrown the front up there to see what everything will look like yet. Did you "clearance" the housing? (I wouldn't mind a picture.)

    * To the Hardware Nazi* These bolts are for mock up purposes
    For some reason I didn't drill the rear shackles where I had them marked :rolleyes: Good thing they're longer than I needed them to be.

    [​IMG]

    Here's a shot of the front shackles. They're just sitting up there right now. The ones on the outside of the frame rail will sit close to flush with the frame when bolted up.

    I used two pieces of angle iron welded together for a spring perch, and had it overhang the cast housing a little. The inboard u-bolt solution is a bit hokey, but it works fine. I bent it just a hair to reach the stock location.

    Pics were a bit hard to get with the plow in the way. I hope they make sense.

    Just trying to burn some time so I figured I'd try out some new carbide burrs. I had some sbc heads or this f134 exhaust manifold. I'd rather destroy this exhaust manifold...
    Mainly was focusing on the roof. This thing is a total mess of rust and carbon buildup. Extrude honing would be much better but you gotta pay to play.

    Picked up 2 ft of 1/4 2x2 angle iron yesterday, made the rear spring hangers, and added 1/8in 1x1 angle iron to the rear of the frame. Hopefully it'll be a bit more rigid.

    After reviewing the pictures you posted above I have to ask, is your tie rod--being octagonal--made from an old Sharps or Winchester rifle barrel? If so, you are the absolute master of repurposing. :bow:And, if so, my condolences to the gun's family. :cry:

    Hahaha!
    No, I found a sweet stick of hexagonal rod in a scrap yard that I drilled and tapped the ends for 3/4" heim joints.

    Ignore the "welds". I've been having some trouble welding horizontal and vertical. :( Push comes to shove I'll buy a mig welder and shielding gas.
    I'll be surprised if the rear holds together.

    Call me Mr. Rig :lol::susp:
    I painted the frame with the most runny paint I've ever sprayed (getting put in the back). And lets thank the 2A for parts and pieces. I think it'll be rebuilt as a faux M38?
    So anyone see any problems if I mount the shackles at the top of the frame like I have them now? I'd make them a few inches longer as well.
