1) I can see the reason to have a thrust wsher to stop axial movement of the distributor shaft but isn't the fibre thrust washer (A12181) sold by the usual suppliers going to wear out within the first few thousand revs? Surely a steel shim washers would be better?
ALSO. 2) What is the logic for having a plain washer under the lock washer of the cam screw? (no part number for the plain washer but it's item #33 in the Brattons/snyders exploded diagram)
