Pins on S900 too far apart

I received my S900-28 balances the other day. Thank you for the quick delivery.
I am installing the parts and the ends do not match my original to fit in the tilt shoe.
I have included a pic
My window is a Better Built 4050 tilt insulated glass. Built in 2004 or 2005.
I selected green tip. If this show in the pic. It is a pale green. As will you notice, the pins in the new balances are further apart. Just enough that the extra length will not allow the spiral to go into the shoe. What do I need to do?

Please see the pivot shoe photos

Hello. I just realized that emails from Swisco Experts were going to Junk box. Just found your post. I had included pics of the shoe in a previous email. But I will attach again here. One with the old balance and one showing the new balance which will not seat as described. Another pic to show the AAMA listing Maybe to verify this is a Better Built window.

Thank you for the update. I will try and modify. But before I do that.
1) You are certain that I we can no longer get the OEM type balances.
2) If I have problems doing thie modification. Do you have pivot shoes that could replace the ones in the window now?
Thank you for any help.

When I ask about the pivot shoe replacement. I mean a shoe to fit my window. But will work with the balances you have.
