ford wrench
 

A friend gave me a Ford wrench and I'm not sure if it's an A wrench or a T wrench. It's a box wrench with designation of : Ford USA 01A-17017B M 68.
The M is in a circle. The sizes are not marked but appear to be about 11/16 on one end and 3/4 on the other. Anybody know what it is?

The "01A" prefix indicates the wrench for a 1940 Ford.

If you are more of a visual learner like me, then here's a handy Ford spark plug wrench part number guide that might help:

It probably was, with a slightly different number at the end.

I've read that there are lots and lots of Ford wrenches. Every car had a set and even though the cars are gone, the wrenches survived. I have a couple and use them on my model A. Brad in Germany posted about the sparkplug wrench and it's still handy due to the bend in the handle for sparkplugs and the drain plug on the pan.
Guess Henry knew what he was doing.

One learns something here every day... Thanks Marty. I 've been wrenching on my "A" for 50 years and never realized that the oil drain plug was 1-1/8" same as the spark plug wrench.

I learned that when I needed to loosen the spark plugs and realized my only wrench in that size was under the car where I was draining the oil…

Hint - you can use those nice copper crushable spark plug gaskets as oil drain plug gaskets.
