@hazetguy, I had a Trek 660 that I bought new back in 1985. I loved that bike; rode my first century on it.
So many innovative touches, such as the cable running through the chainstay and the seatpost binder bolt built into the lugset.
I think that I still have the original Modolo brakes and “resin” body rear derailleur, plus assorted other original parts.
You have done a great job returning that bike to life. Congrats and thank you for sharing those pics.
