I have a 2015 SGS with stock wheels. I have my buddy's Prodigy wheels from his 2020 Road Glide Special and I am wondering if they will fit on my 2015. The rear axle part numbers are different, 2020 PN 43000207, 2015 PN 43000213 however, I spoke with Longstar Harley today and they said both rear axles were the same diameter. Additionally, if you order rear wheel bearings, they are the same part number for both models. Has anyone made a change like this or have knowledge on the subject. BTW, the swing arms (rear fork) are the same. Please let me know.
