Yes 351 or 390 look right but my shoe looks slightly different will it still work. I can't tell any difference between 351 and 390
My channel says 21 D but the actual length of the metal is 22 the other window says 19 but the metal is 20 inches, what length do I order?

The style of your shoe is fine, what's more important is the depth. We have detailed dimensions on each balance showing what shoe they come with, and how big those shoes are.

Your stamps and lengths make sense. A balance with a 21 D stamp would be 22" long, and so on. Keep in mind that your old "21 D" stamp usually corresponds to our 2140 option.
