I have a 12 volt Chevy/GMC starter with a 9 tooth pinion. The starter woks very well. I bought it by mistake. I thought it was a standard starter with a 10 tooth pinion gear. My old GMC engine and flywheel and entire 40 Chevy nearly shook to to pieces when I tried to start it up. Lucky for me I shut it off quickly and nothing was damaged. I still have the starter and would be glad to ship it to you if you can use it. Hope this helps.
