pictures of balances and pivot shoe for identification

As arranged during today's telephone conversation, I am attaching
pictures of balances and pivot shoe that I need.

I need six (6) 22" long 9/16" wide balances, and four (4) 28" long 9/16"
wide balances. Also I need 10 pivot shoes - when I am measuring the
pivot shoes. I get dimensions: 2" long, 1" wide and a little bit less
than 9/16" deep. Original window manufacturer - Florida Extruders International.

Regards,

1) You say that I should order the s770 channel balance # (length) that matches the # stumped on my original balance. But the numbers stumped don't much the actual lengths of the balances when I measure them as instructed on Swisco website (end to end of metal channel balance). Number stumped are 21F and 27E, while actual lengths are 22" and 28". I am not sure if Swisco is aware of it, but please advise.

2) The two 15-179 pivot shoes you specified seem to bE OK - I just need to know what are dimensions of the opening into which the window sash pivot bar needs to be inserted. My pivot bars are 3/16" x 5/16" and the openings in the pivot shoe need to accommodate them.

Thank you
