Classic to bugeye back box ???
 

Will a classic back box fit straight on to my 02 bugeye ?

Yes it will fit straight on, you just do not use the front hangar,which is fine as it is the 2 rear hangars that take all of the weight of the backbox.

...agreed, the front hanger points the opposite way on a classic to a newage so you can always weld it on the other way round if you wanted to use it.
