When I was in high school, "dropout spacer" meant something completely different.
And an '84 LeTour sounds like something to drink, not something to ride.
Anyway, here goes:
My '84 LeTour has this spacer in one dropout:
Questions:
1) is there supposed to be a matching spacer in the other dropout?
2) if no, does the spacer belong on the non-drive side?
3) if yes, I am ISO/WTB ... does anyone have one to spare?
4) then again, should I just remove it?
