quick update....the saddle cover's coming off, unfortunately. Dunno if that's a big issue or not. I really need to get a bikestand - trying to levitate the thing and reinstall the back wheel (when you haven't done it in 25 yrs) is a trick or two.
About all I got tool wise is a universal allen wrench set, pliers and screwdrivers. The flickstand thingy and rear rack are coming off, as is the computer wire on the fork. Frame's a nice sturdy little beast - I can see why lugged steel frame Treks and the 520 in particular are so desirable.
Yep, bought it to ride (a lot, hopefully)
