Ended up going with option D, lol. Ran across some Ridetech coilover brackets in the for sale forum and figured they'd work nicely. Had to add a hole for the leaf spring bolt to protrude. Nice thing is they'll allow me to use the 14" shocks I already have. Waiting on the billet lower mount and I'll have this issue wrapped up.
I also got the Hyperco springs solid mounted as Ridetech does with them in their StreetGrip setup. A .5" (top) and .25" (bottom) aluminum lowering block Serve to take up the added depth of the multi-leaf mounts and allow a good grip/crush on the composite spring.
