flywheel

I had posted another wanted recently for a smallblock bellhousing. early A Bob came through for me on that and I got a bellhousing from him with part no 2536940. It looks like it was for a 3 speed and a 10.5 flywheel.

This is really just for starting the engine without needing my 727 tranny. So just trying to find an old flywheel that will work for that. I am getting a bit confused because I see both 130 tooth and 143 tooth listed both as 10.5" flywheels. I don't see hwo both could match up with the starter.

So if anyone has an old flywheel that they are looking to sell and or can help me with what I need that would be appreciated.

Thanks
