I believe I'd prefer to stay with the heavier 3/4 ton spindle/hub assembly, and fabricate an adapter plate to switch to the 6 lug bolt pattern. That would require about a 1/2" thick disc of steel attached to the existing hub with flat head Allen bolts, drilled for the 6 lug bolt pattern. Not much of an effort for most well-qualified machinists. That would also allow the use of an 8 lug disc and caliper for better braking capabilities.
