Generally speaking, you need to match the model, the part number up until the hyphen, and the 2nd & 3rd digits of the serial number. Then go with the closest date code you can find (preferably within a couple months).

Then, once you have the donor, check if the preamp type is also "72" in terminal to confirm that it's the same (sometimes it isn't). The second byte "21" really doesn't matter, it's only the first byte that's important.
