I have an Ideal, I bit far fetched, could call Lone Star do a group buy on there CNC front hubs for the Banshee spindles with the 0.200" step modification  and the  4 x 144 pattern and see what happens, say 10 sets, might get a deal on price, might pass out from there pricing.
FYI Mike, you can get a LTZ400 hub, spindles, brake, rotors for less than $125.00, plus we will need rotors for the new hubs.

FYI the LTZ400 rotors are the same size as the LT500
