Dang, wish I was closer. Need an RD60 headlight that is no longer
available for love or money but a GT80 shell could fit (and look
right I think) and that is available. That GT80 you got have a headlight
and ring?
Problem is you can't get a headlight that works for an RD60, or at least I
haven't found one. The GT80 shell is slightly larger and a ton of bikes
use that headlight so that they are available.
