i found the "Holy Grail" 12v but its a dually and i dont want one so i was wondering are the rear ends the same as the single wheel axles it has a flat bed so i dont have to worry adout fenders and i know the front ends are the same cause it has bolt on spacers there so can i use the axle or do i need to buy a single wheel axle

 

they should be the same just need standard wheels rather than the dually offsets and you should be good to go.
