Those are not ordinary fender washers they supply with the PR. They are about 3/16" thick, and 2 3/8" diameter. As in the graphic- those weighed a range of 65-67g per disc, so they are not light either. 3x 1.5" zinc fender washers from the average hardware store at 1/16" thickness, and then the lock-wingnut. You can use thread locker and a lock washer instead if you so choose, but the wingnut holds well in my case.
I did not weigh the entire mass myself, as it was measured to hit my tuning and not the mass required. I would strongly suggest you measure the tuning if at all possible. There is bound to be unit to unit variation in actual Mms of the PR itself without mass attached.
