Window Slider Part Replacements Needed

Question

Included are photos of the part which needs to be replaced in six windows (both sides of each window), so we need six sets (12 pieces) of this part.  Though the two parts removed from the window appear to be the same other than where the coil is attached, one is marked "20 4" (with the slightly shorter coil), and the other is marked "20 5" (as you should be able to see on the image with both parts shown).             From end of white plastic to the other end of white plastic is 22" on both.  Thank you so much for your help.

Hello,

We can supply your replacement balances but it will need to be a custom order due to the length, extended travel pulley system and unique combination of end attachments.

With that being said, both balances should have the same stamp code. Since yours are different, we'll need you to confirm the exact weight of the window sash to choose the correct spring strength for your replacements. Also, these balances should have a 20-5/8" long metal channel, not including the end fittings. Thank you!
