My truck was born a 3 speed on the column. It has passed down in the family and my dad had converted it to 12V. It always had a 6V starter on it and other than turning over faster, it never gave a problem. It started easy going faster. Then I found a hydra-matic frame and driveline. I switched it all over but kept my engine. The H-M uses a solenoid starter. Knowing that finding a new flex-plate/flywheel for H-M would be a chore, I took the starter as mentioned to the local specialist. They gave the advice that while the starter motor would be fine with the 12V, the solenoid would work but they felt it could hit the teeth too hard so they matched the original solenoid as best they could with a new 12V version they had on the shelf. It never occurred to me to ask what its original application was for, in case it ever needed to be replaced. I just figured I would match it up again if that day ever came. This looks to be a very similar part.
