MSD 6AL-2 PROGRAMMABLE Ignition Control in a Squarebody, say what?

so got the HEI vacuum advance eliminator kit Part No. 88364

the kit comes with two random screws that some disgruntled employee threw in not even looking, the larger longer screw did not even thread into any of the holes in the distributor cause it was too big, luckily I re used three of the original screws from before

[Gregski]

so lessons learned so far: you need to lock out both the mechanical advance and the vacuum advance, or if you are made of money just but the MSD billet aluminum distributor without the vacuum advance, that one allows you to twist its head into the locked-out position, and Bob's your uncle

alright one more step and we are done manhandling the distributor I promise, although the instructions don't mention this, it's the topic of Rotor Phasing, say what?
