Bump.  Would someone with original hardware be willing to measure the ID, OD and thickness of the washer on the top shock mount?
Mine are about 10mm ( probably 10.3) ID, 21mm OD and about 1mm thick. OD of stud after threaded bit about 16mm. So I think you need to find some washers say 17mm ID and 21mm OD to take up the space as well as the original size washer to butt up against the shoulder.

Thank you Cliff!  Can you tell me, does the acorn nut and washer actually tighten down against the shock top, or the bushing?  Or does it tighten against the unthreaded spindle, leaving the shock top and spindle loose?

Acorn nut tightens washer hard up against shoulder and and slightly squashes rubber but does not touch shock absorber itself.

I was able to cobble together some washers and bushings (which just fit over the mounting spindle) to tighten things up against the rubber bushes, but not clamp down hard on the shock mount itself...
