I need to replace (8) of the 31"x 1/2" springs pictured, with the 2930C marking.

I also need (8) 31"x 1/2" with the marking 2910T for smaller windows.

This appears to be either our S351-30 or S390-30. The only difference between these two channel balances is the depth of the bottom nylon shoe, or 'heel-to-toe' measurement, so compare both with your old hardware to see what matches best. Choose stamp options of 2930 and 2910, respectively.
