They will interchange. Infact, the hubs sold by GM these days are the same ones that came on the early 90's Dodge with Budd cast into the outer diameter of the hub. They sort of neck-down after the locking hub as opposed to the GM units that had a machined surface from locking hub to wheel mount area. IMO, GM units look cooler, but the Dodge ones are the same, just appear a bit different on the outside.
