Hi Sean,
I purchased two sets from two local suppliers in Australia. One was an MCA-304 set for the large journal A10 crank - 10,6, & 2 thou. The other was an MCA-H304 set for the early A65 - 10,5, & 3 thou. The third set was an A10 set from OneStopBikeBits on evilbay. They were unmarked, but were advertised as 10, 6, & 2 thou. I also had the same problem as Berger, where I got a false measurement but for a different reason. Some of the shims had been pressed out of sheet and had some overflow. I dremelled that off carefully. All shims were the same diameter. The shims were also about 1-1.5 mm over the shaft diameter. I presumed necessary because of the radius. I mounted the crankshaft vertical but lightly in the vice ( using heaps of rag & cardboard so as not to damage the Timing side journal), placed the shims as centrally as possible, and dropped the inner race over and clamped it down with the cush sleeve, spacer & nut. When the inner cooled, it clamped itself very well. I didn't use Loctite, but a tiny drop of Loctite 641 may have held them in place with more surety. Anyway it seemed to work OK.
I remember doing this with my old A7 in 1969 - don't remember knowing or doing any of this.! That bike was as reliable as you could want. Makes you wonder why we are so pedantic. We know too much these days.!
