So I went to Mecca... took the leaf springs into Summit Racing.
That said, IF you were to leave the Outer Liner in the spring eye, and machined the bushings to have a different inner steel spacer and cut the bushings down, you could use a 73-77 F250 4wd Kit.
If you just wanted to machine the outside and replace one of the inner steel spacers (on each side), you could use the energy suspension '3 bushing shackle' setup, but it does not have enough of the inner steel spacers of the right size to do the job....
Caveat... I removed the original outer steel bushing retainer.... if that were left in place, the 73-77 kit would be EASIER to machine to fit, but would NOT directly fit.
I will be calling Prothane Monday to see what they can do....
