I don't have an answer, but check out the above length for some suggestions. Good Luck.

My Denso Mini conversion needed a 23” belt. I used alternator bracket from Brillman. I bought belt from Advance Auto.

Cub is a 51. 21 inch looks like it will work.

This particular application took a 22 inch belt.

Late to the party, here, but I used a 22” on my last one. (3l220) if I remember correctly.

We tried both a 21" and 22" belt. Although the 21" would have worked, it did not allow the alternator to swing enough without hitting the water neck on the cylinder head to get the belt off in the future, if needed. I was using the alternator bracket from Steiner. In the end, the 22" was right on the money.
