My buddys truck was a single wheel....then he converted it to a dually...now he wants to go back.....im not sure what he did with his rear axle....he might of used spacers....but i dont think he changed it....he also has a dana 60 up front but im not sure if he's running dually rims up front or not....I just know that when he changes it I could get it for cheap....and I like things that are different....a single cab dually with a dana 60 and 4" lift....now you dont see that everyday...I just dont know what I wanna do about my rims....He has chrome covers for his...they look pretty bad....I was thinking of adapting the newer style 5 spoke dually rims to my truck....if I gotta run spacers why not make them fit the newer style rims....
