1/2" channel balance with stamp 2740

A quick learner from Cardiff, CA says:
This is from a mid 1990's vintage aluminum double hung non-tilt window manufactured in San Diego, CA. There is a stamped number "2740"; metal part is 28" and 9/16" wide.

Can you identify? Need 4 ASAP.

Thank you in advance! Hope Hurricane Irene not too disruptive!

Thankfully hurricane Irene was not too bad in our area (we are located right across the Delaware river from Philadelphia). We were a bit worried about the Delaware flooding out our area, but luckily it did not.

You need to order our S385-28 with the 2740 option.
