Actually just a clean up. I'm dropping a 390 in a '78 F150 and plan to use this Duraspark electronic distributor. I have the gear and lower collar off. Should the shaft push out the top? There is some resistance. Not sure if gunk build up or something else. I don't want to force it and break or bend anything. Does the reluctor just press off an on? How do you know how far the reluctor goes on the shaft at reassembly? Are there any good exploded diagrams available?
thanks,
