Thanks for the input. Yeah, replacing the lug might be a bit crazy. If I could do it myself, I might go that route. I use two strips of shim stock, cut to nearly the circumference of the steerer. Race goes on, then I fit the shim stock in one at a time. Pretty tight, but of course not perfect. Bike has always ridden fine, including no hands, but bothers me cuz it isn't right

The International frame I had before I had the same fork problem with (fork blades slightly misaligned with the crown lug). The same machine shop milled that one perfectly; why they decided to screw this one up I don't know.

As for dimpling the seat, is this done from the top edge (parallel to the steerer tube), or the face (perpendicular to the steerer tube)? I may start with this approach.
