Finally got around to pining the 18mm socket to the MSD distributor shaft, using an 1/8" roll pin. Now we don't have to worry about the socket falling off inside the head when removing the distributor. Plus, there is no movement/play between the shaft & socket. Total runout of the socket to centerline of distributor shaft is within .002"..

Next, I will be machining an offset bushing (Jeff's idea) to align the distributor socket to exhaust cam bolt. I will be turning down the aluminum base on distributor and make the offset bushing to fit the cam cover boss I.D. to the new smaller distributor base O.D. Then I will machine a new, smaller O-ring groove in the distributor base for oil control. The offset bushing will be RTV'd to the cam cover boss, once position is found.

The bore in the bushing will be offset from centerline about 040"-.050" and able to rotate inside the cam cover boss, this will acheive the best alignment possible. Jeff will be getting the dimensions as soon as I can get the distributor to him. Once all is aligned with offset bushing, I will drill/tap for a set screw (maybe 2) to secure the distributor and bushing to cam cover boss. This will eliminate any possible movement in distributor timing.
