Not to sound snooty, but I am going to take the easy way out!! Wilkinson has a set of ALL FOUR calipers rebuilt with OEM parts for ~$500 with the old ones as core exchanges. Given the cost of the parts, the math is in favor of "the easy way" !!!! The owner simply wants his car to work when he wants to drive it, and OEM worked fine for from 1972 to 1990.

Frankly, in another eighteen years, the point may be moot, if you get my drift.
