On my Taco with 63s I have the stock Chevy shackle bolted to the stock Toy shackle. The Toy shackle sits against the frame when not flexed. Then swings down to give awsome droop while flexing. The shockes are in the stock location and limit the droop, for now. But I need to move the hanger to give a better shackle angle and a better ride on the street.
But for your situation I would suggest moving the hanger back a few inches by grinding the welds and rewelding it.
For my Runner I bought the cheepest ones I could fine, $20.
