Converted my 1949 3600 to 12V a few years ago and kept the 6V starter. Unfortunately, the 6V starter is on its last legs intend to replace it with a 12V starter. Any recommendations on a source for a 12 volt?

A 6v starter can be used with a 12v system without any problems.. Just don't hold the key for long time if it doesn't start in a few seconds.
Switching to a 12v starter will require a new flywheel since 6v and 12v starters have different gearing.
Have the old starter rebuilt. There are a lot of qualified rebuilders. I'm sure there is an old time auto electric place up there in Detroit that can rebuild your old one.

I had funny noises in my 6 volt starter years ago and solved them like this.
Still working well on 12 volts now.

A six volt starter will turn the engine over faster than a 12 volt starter believe it or not. If the bearings and brushes are in good shape, they work fine last long time. I drove my 3100 all the way across a level parking lot with the key off. I mashed the stomp starter, let the clutch out gingerly in first gear and off I went. I couldn't go fast enough to shift into second before I ran out of parking lot. Starter survived just fine.

Thanks everybody! Didn’t realize the fly wheel would have to be changed also. I will look for a rebuilder in my area. What would I do without stovebolt.
If there's nobody local, NAPA can get a rebuilt starter with a good warranty overnight in most areas. Just be sure to specify 6 volt. (1954 or earlier) There's a difference in the angle of the pinion teeth and the diameter of the armature shaft from the 12 volt units. The 6V has a shaft about 5/8" in diameter, while the 12V models are close to 1/2". If the original ID tag is still there, 12V starters have a red tag. 6V ID tags are black. Jerry

Yes. I bought a brand new a starter from NAPA for $79 last December. I kept the original 1949 one because I thought it was worth more than the $19 core charge. Maybe I'll rebuild it someday.
