I would be interested in this service to, I want to check my R engine this year.
I have 16 spare shims plus of course the 16 in my R and 16 in a spare 1100F engine. I will check the sizes I have and post the results here, I will also call Simon if any are good for him.
Maybe in the garage section we could all just list our shim stock for all to read and just delete/relist as we swap them between ourselves.
Graham.
