It is big. I had to bang out the tin to the left. I'm hoping that the cooling flap still moves freely. It was very close.
Slits-How do you re-index it as this is a vac adv unit??
Place the engine at TDC #1. Remove the dizzy. I can't remember the size bolt that you can "screw" into the center of the dizzy drive gear, but screw it in (or any other way you can pull the dizzy drive gear up) and rotate it counterclockwise. Look at the relation of the larger and smaller part of the circle on the dizzy drive gear (drive socket cuts the circle) and get it into a postion that the dizzy vac advance will clear what you need to and reseat the dizzy drive gear. Hopefully, if there are shims on the bottom of the gear they won't fall off into the case.
Alternatively - if the Mallory is like the stock dizzy, there is no stop on the rotation (except for the vac advance hitting shit) - you can turn it 360 degrees. If you set the engine at TDC #1 as before, and mark the dizzy cap pole that is #1 and the position the rotor is pointing to on the case of the motor Then just rotate the dizzy (counter clockwise) until the vac is in the position you want (you can even remove the vac advance if you have to - and them put it back on after you establish the realtionship). The pole that is nearest the mark you made on the case is the new #1 now. Unplug the wires from the dizzy cap and plug #1 lead into it. Follow the firing order with the rest in a clockwise rotation. This method saves pulling the dizzy gear.
Hope this helps. I can visualize it and hope it translates.
PS: Make sure those cooling flaps rotate!!!!! Or at least stick them in the open position. Remember, the dizzy isn't a brain and doesn't care where #1 is located as long as the rest of the leads follow in firing sequence. The marks that the factory put on the dizzy, etc are for reference only
