patrick, the pin is the same size .125 but it is 1 inch long the dis gear is 3/4 long, msd uses a different pin it looks like a double rolled pin the ones you buy at home depot are not like that, also i have .006 side play in the bottom of the shaft where it comes out the aluminum body i called msd threy said it is normal the
oil pump shaft would take up the play. i dont think taht souns right i have a lot of money in this motor i want to make sure it will be ok, so far nobody i know has a new msd 8594 dis in stock so they can check it.
msd said those pins are specially made for them i dont know i have to check?.
