Look on your screen to the top-left. Click on Tractor parts, click Ford, click Dexta, and click electrical.
Starter on YTMAG site is selenoid engage, key or button push, which eliminates the handle, rod and large relay. I have done three of these and they are simple to install. The good news is they are a faster turning starter. The good news is they make what you think is a tired engine, burst to life with a bump. Other than not being "original", there is no bad news.
