    In addition, that long drag link combined with the difference in angle with the radius arm will probably make for some interesting bump steer.

    LOL.. so here's what I would do for you if you if you brought this to my shop,,,I would make a block just like you ask'd and put it on top of the mount you have, drill four holes in it , and make it long enough to to go on the cross member... I would take 1/2'' stock, use my plasma table to cut a block to fit with holes for the u bolts I would weld the block in and mount the spring on top of the mount like you ask'd and be done... it will work with the spring you have...and the shackle's... they will work as is.. but not 100% correct... but will work... to fine tune it you could get the correct spring and shackles...
    this is my RPU front... it's perfect. spring on top. rides and drives perfect,...LOL been down the freeway 1000's of miles through the years..

  9. Too much science and not enough action, just do it ! It'll be fine.

    Run shocks, bump steer and wheel hop can be hard to get out of at a higher speed.

    That spring will permanently bend (distort) or break with that reverse curvature at the perch.

    it has two leafs on it now and no reverse curvature, that was just a pic with one leaf as a reference.

    It's going to have barely any spring rate with only two leaves. Standing on it in your garage is nothing like driving down the road. You'll be putting that axle into the crossmember.

    If OEMs could get away with using just two leaves, they would. Monoleaf springs are designed and constructed differently than the main leaf of a multi-leaf spring.
