MG Thank you for the link to Ebay. The book I have is green but different purpose. The one you show is also available from Rock Auto, also at a price of $53.99. I ordered one from RA along with some other parts. Ebay is good place to find stuff, but not my first choice.

Thank you for all the posts fellows. Is the "green book" you refer to the green 1939-1948 Service Manual, Passenger Cars and Trucks (which I have) or is there another "green book"? If there is, what is its full name and where can I get one.

The OP said that the 11A stamp was on the cam and weights assembly (11A-12176). These parts will fit the 21A and 59A distributor. The shaft, P/N 11A 12175 will not fit the 21A or 59A distributor. The 21A-12175 shaft is only used for the 21A and 59A pancake distributors.

Ken, The '42 (21A) shaft doesn't fit the helmet distributors, but the '41 (11A) shaft does fit - the '41 has a helmet type distributor. I didn't see the second bushing in the diagram of the 21A (pg. 506) but it is shown on as part #12120 in the exploded view of the "distributor breaker" on pg. 515. Thanks, I learned something.

I can't explain how an 11A-12175 shaft could wind up in a 21A or a 59A distributor. In the Green Book (Ford Chassis Parts and Accessories Catalogue - cars '28 - '48 & trucks '28 - '47) the table on page 518 shows that the 11A-12175 shaft fits only the 11A-12127 distributor. (I know it will also fit the earlier 68A distributors like the '37 to '40.) These "helmut" type distributors have a bushing at the front (#12120) as well as the back. The table shows that the 21A-12175 shaft assembly fits both the 21A-12127 distributor ('42) and the 59A-12127 distributor ('46-'48). These distributors only have the bushing at the back, the rotor goes on the front. Are you certain you have a '46 (59A) distributor? Is it possible that your car has a '41 engine? You can't use a '41 (11A) distributor on a later engine without an adaptor. Also, I can't find a part #12181. However, part #11A-12187 was the number assigned to the original shaft, cam and weights assembly for '41. Perhaps you should invest in the Green Book. The distributor section is 19 pages long and it has great diagrams.

So the 11A is from a '41 and showed up in a '46 bail type dist. Is the advance curve going to be an issue? Would that be why someone put a spot weld on the cross plate to restrict the weight travel (see original post). I wonder if Johnny cash owned this car at one time?
