Will the t locks you sell replace this one?

This looks like the 1" 15-194 T-Lock Shoe, just look it over to confirm. However, you'll note that your old shoe has a groove in the stem, that interfaces with a groove in the metal channel. Both our balances and shoes lack this configuration. I am afraid this means you'll need to replace not just the shoes, but the balances as well. See our Series 795. This blog article here discusses more about this balance.
