Just wondering if anyone has done a 250 rear conversion on a 17 softail that isn’t a heartland kit.  Does anyone know if you can buy an offset kit for the 17 models? I’ve custom made my own swing arm  and now have struck the problem of having to offset, main shaft ect.  Can you just buy a already made kit somewhere without having to buy the swing arm?  I’ve seen zodiac have a few but not sure on if they or any of them fit the 17 softail.  And are the gearboxes from 07-17 the same ?
