The axle is bolted to my spring right now but I haven't go the hubs on. I'm trying to figure out the most efficient way to get my hubs and everything around them mounted. I have dually front hubs, dust shields, and backing plates. The options I'm looking at are: 1. Machine my hubs down. ---But which calipers, rotors, wheel bearings, and wheel studs do I use? 2. Buy the SRW hubs found for $185 each then buy the matching backing plates, bearings, calipers, and what ever else. 3. I don't know what 3 is but I'm sure there'll be a 3 soon enough.
