Do I have the Series 351?

I'm replacing a non tilt block and tackle window balance from a single hung Milgard window. I'm not sure this is the original balance. The metal is 33 inches long and 1/2 inch wide. It is stamped 3240. Images of the ends are attached. I'm thinking of ordering the 33" Series 351 Channel Balance, S351-33 option 3240, but I want to confirm this is the correct part. Thanks.
