You are absolutely correct. The older I get the more difficult is becomes to tell my right hand from my left… lol!
I used the 6402 freehub body, lower right, on an FH-DX650, to run an 8 speed cassette.
Ebay is most likely the only source for older 7 speed UG/HG freehubs. It is hit or miss, but try to find one that appears to be well kept and little wear marks. Every now and then an NOS pops up, pretty expensive.
I’ll soak an older freehub body in citrus cleaner, blow out the excess, let it dry thoroughly, and then let Phil’s oil soak into it until it quiets down.
