8) what year 170? the early ones have a smaller shaft, and use a 1/4" drive shaft for the pump. after the first of the year in 1964 ford went to the large shaft and the larger 5/16" oil pump drive shaft. if you have the early block you have a few choices;
1: swap the points for the pertronix system. you dont lose the load-o-matic though.
2: you can contact addo, or xecute, or one of the other members from down under, and have them send you an electronic distributor from an aussie six. they use the early shaft size, but need the larger oil pump drive shaft.
3: you can ream out the guide hole in the block to allow for the larger late shaft. again you need to use the large oil pump drive shaft and the later oil pump.
