Dave,Back in my big block modified days I was partial to leaf rears and used the composite leafs.I think we got em from AFCO.We made front mounts with a closed top and vertical slots for the front eye thru bolts and welded a 1/2 ? nut on the top plate and ran a bolt that sat on top of the spring eye for weight jacks. We also ran some home made sliders in place of shackles. They worked pretty darn good.
