Sure slap it in. Did you have it apart? Is it good to go? Don't see many ferguson sherman. I pull this one out of a TO30. It's a ford case that has been altered. Top, one on the left. The back of the Case also altered to fit. If someone needs it to fit the ferguson and has the ford case I would swap.
I could tell you where to locate the hole on the ford. I guess it's best to put it in and take measurements. Drill a small pilot hole before you use the holesaw to make sure you are on the money.
