Itsy bitsy, tiny problem wit those post 1985-1990's Ballooner fenders and old ballooners. I have a set from late 1990's that I scrapped thinking I could use on old frame.. 90's and newer fenders are mounted differently and,, They're not as wide as regular about 3-1/4" pre-60's are. And much smaller than Phantoms extra-wide. Rather, like a 3" wide middleweight ballooner that never existed until the 90's Classic's Taiwan and Chinese Cruiser frames .
I never tried to retro fit them and expect rear frame indented space is goanna be sloppy lose on the rear, while fork springer indent should fit on 1955 through 1980 'New style' springer that's about the same as 1990's are. .
