I have a 1988 GMC Suburban V10. It has axles out of a 78 3/4Ton. I'm changing the axles for a better gear ratio, Rearend is the same and on the front Im going from a Dana 44 to a GM Corporate 10 bolt(8 Lug). My question is are Warn 9072 locking hubs and 20990 locking hubs interchangeable if you swap the hub and rotor as well. One is the flange style and other is straight. Here are some pics I found online of the two types of lockers. Any help is greatly appreciated.
