Did alittle Googling, and only found 1 reference to using 2nd gen adaptor's on a 1st gen axle.
I realize the adaptors would need to be machined to clear the lockout hub, but wonder if they still would have the strength to be proper adaptors.
The reason for this idea, is being able to upgrade to gen 3 brake calipers and rotors. For those who don't know, the rotor slips over the hub/lug studs, vs being held in by the lug studs. Hence not being able upgrade a dually.
Couple different options,
* Run srw hubs, and machine 2nd gen spacers,
* Run srw hubs and billet spacers
Both options still allow dually wheels, so only need 1 spare, and can rotate as nessicary, vs just running srw hubs and needing 2 spares.
Truck needs new front brakes anyways, thought it would be a good time to upgrade if possible. Always been kinda disappointed in the stopping ability when loaded, and haven't found much in the way of aftermarket performance pads/rotors
