John,
Laterally, this is not an excessive amount of play! In operation the
distributor does not operate with a side load on the shaft, the shaft
floats. The best method is to "MIC" the shaft and then, using a
telescoping gauge, "MIC" the bushings. Using this method the variance
really should be no more than two thousandth's of an inch.
>From what you have described, I doubt it is.
For a test connect a dwell meter and rev the engine. If the meter
fluctuates when decelerating then the shaft is "walking". The dwell
should remain constant within a degree or so...

Jim, been out on vacation so havent read my emails lately. I took the
entire distributor apart, so all I have is a housing with two dist shaft
bushings and a shaft with the cam block/advance mechanism in place.
With the dist in a vise, I used a dial indicator to measure the
side-to-side play on one of the cam flats, which was 0.0035". If I take
off the cam block and measure the shaft side-to-side play by itself I
get 0.0025".
