Found a image of the rear cassette for same bicycle on forums: http://www.bikeforums.net/classic-vi...ng-bike-2.html

Washer, large spacer on the left. Wish the angle was better on the photo, and I would like to see more of the right side, info to understand if i am missing a part, since there was no diagram available for this assembly.

mrrabbit, 36.00mm - 37.00mm, this more than i have currently. To me it must be less than this measurement, as the cassette is to far from the right dropout, and the left has no clearance. maybe with this cassette the spacing is different.
