Finally got my cam back and reinstalling everything this weekend. Ran into a little dilemma. The distributor drive figure in the Haines manual shows that there is to be a washer between the top of the oil pump bush and the distributor drive gear. First of all what is the process to get the correct measurement for A&B for the thickness of the washer? Suppose to be a 5k end float at A. second is that Moss does not show this washer in any of their illustrations so I would have to believe it is not available at lease thru them . When i took it out I don't remember there being one but there are 2 stacked gaskets for the distributor.
