The Ford Barn - View Single Post - Correct springs for a Load-O-Matic distribator

Load-O-Matic distributors vary a lot from the flathead to the Y-block and various 6-cylinder applications. They were around quite a while.

If Southside Obsolete can't help, I'd say start looking for another post 1950 Mercury distributor. Fords and Mercury cars used the same basic distributor body from 1950 when they changed to the open shaft with the lower tip support boss in the timing cover and all of the flatheads used the same primary weight spring in the applicable distributors and some used the same spring for both springs. The change for the diaphragm spring was started for the OCM-12127 distributor for 1950. The primary weight spring is P/N 7RA-12192 and the diaphragm spring is the P/N OCM-12226. These are the part numbers for flathead 255 CID Mercury cars from 1950 through 1953.

This little change is basically all that separated the 239 CID distributors from the 255 units otherwise all the other parts interchange. These things will corrode if not well stored so a person need to verify they are usable.
