Can anyone tell me the size of the spacers I need to swap a 80s disc brake rear wheel from a sportster onto a 77 ironhead with drum that's hardtail?
Also I'm guessing I need the larger axle as my stock axle is smaller diameter

Hope someone has done it before but it depends on what hard tail you used there are many variables........ Do you have a dial caliper or something to measure with??? That will be your best bet.......... Good luck.....

This won't answer your question directly, but be aware that there are 2 different rear wheel configurations for 80's Sportsters. One for dished sprockets, which is first type, and then one for use with a flat sprocket. Mix them and the chain line will be off. Do some careful measuring to determine what spacing you need. Either type can be used with the proper spacers.
