O.K. final follow-up on finding/making a replacement rr derailleur pulley.

Got my Shimano pulleys today. The sleeve bearings have a very small diameter with a resulting bushing wall being only 1.38mm thick. IF it could be drilled/reamed out to take a 6MM bolt that would leave a .995mm sleeve wall. Doesn't really matter anyway because the sleeve bearing is hardened steel and my drill could not touch it.

So plan 'B' ..... modifying a CURRENT Shimano pulley is not workable (at least for me)
Plan 'C' is using Bullseye pulleys. Ball bearings just like my 1972 Huret rr derailleur.
