1 ton Conversion

[CypressChevy]

Anyone ever installed 1-Ton dually wheels on the front of a 3/4 ton truck Hub? Here is my problem. I have a 1970 chevy 1-ton dually frame, which I installed a 48 chevy pickup cab and bed on it. Ending up with a 48 1 ton dually. It looks great except The front stock 70 dually wheels stick out of the front fender wells, like a inch on each side. I am thinking changing the hubs from 1 ton to 3/4 ton. Then adding a 1 or 2 inch spacer and then the dually wheels, making the front total track 3-4 inches less. Ending up with the dually wheels inside the fender wells not outside.
