Spiral title window balances

I'm looking for 2 spiral window balances for tilt windows. The balance measures 9" long 9/16" of and the 2 pins on the bottom are 7/16" apart. It has a blue tip. It appears the same as your 600 series but you don't offer that in the blue tip is this something I can get?

I need 6 spiral balances for tilt windows. They appear to be the same as the 600 series. They are 5/8 od by 9" tube length with a blue bearing. the ones on the website in 9" length are not offered with the blue bearing and the window weighs 22 pounds so it is too heavy for the ones offered. I also need 4 of part number S600-11 with blue tips and a installation tool 75-033.
