The part was fine, however, I needed a 9807.

Interesting find, my starter was going out on my French flathead. Without measuring the throw of the actuator, I purchased the starter for the French block. Turns out the bell housing required a standard starter (9807) and not this one. So the 9807 worked perfectly. So, don't make the same mistake I did and definitely measure the throw on your existing starter first :-)

Put this on my flathead hotrod easy to fit took about ten minutes. This is the second Powermaster starter I've bought from Speedway for my cars. Great product. Always buy direct from Speedway because of their fast shipping to England.
