Does this starter come with a gasket? Thank you Dennis

Willys Jeep Parts Tech:
There aren't gaskets when installing starters.

I have a 1950 model 673 wagon with an L6-161.Does this starter eliminate the foot switch or is it rigged up for the foot switch? I want to change over to 12 volt and would like to keep the foot switch.

Willys Tech:
It will convert you over to an ignition switch start.

I have a 49 willys pickup with the L head engine with a manual foot start. Will this fit without changing the bellhousing.

Willys Tech:
Yes this will work perfectly for you with no modification on the bellhousing.

I have a 52 Willys PU. about six years ago, before I owned it, a new ring gear was installed. I have counted the teeth--118. Will this starter or any of the starters you carry work with my PU?

Willys Tech:
You probably have a 124 tooth ring gear on there and just miscounted. Please call us toll free. We can help you out on it.

If I purchased the 12 volt alternator you have listed for my 1948 Jeepster-do I also need to purchase the 12 volt starter for the starting and charging systems to all work together correctly? Anything else that would need to be purchased?

Willys Tech:
Your 6 volt is ok, but will be slow cranking. This starter is hi-torque gear reduction. I really recommend it. If you are going from 6 volt to 12 you need to get the regulator (923130) and coil (933160)
