one more iso question

When it's time to replace my iso rubbers, since I converted to vernier adjustable ones, which rubbers do I order? The bike is a 71 that had standard shim adjustable and I put in adjustables from either Old Britts or Clubman racing, can't remember which. Do I order them for the 71 or something different? I seem to recall them being the same when I changed them, but my feeble memory has failed me again.

The front and rear vernier rubber mounts should be the same for all years (pre-Mk3 and Mk3).
