I have found on my 1971 two shim but the oil pump seal was very compressed.

Adjust the quantity or thickness of shims to give 0.010" (0.25mm) seal compression.
Edit. Engines before 150120 had no oil pump gasket (06-2447). If a pump gasket has been fitted then any existing shims may need to be removed.

The question is, can a very compressed seal give problems.
