Broken shoes

Happy new year! I have some 6500 series double hung windows (I think simonton) purchased and installed by home depot in 2010. At least one shoe on each window is broken. I removed the whole balance assembly (had to cut a bigger hole) and pulled everything out. None of the coils have any numbers or letters stamped on them. The top coil wasn't even attached to the bottom one or shoe. I can't even get the barrel for the top coil to fit anymore either.
Are you able to identify these parts for replacements? I would need 8. Thanks.

Thanks. Sash is 26lbs so four 6.5 is needed I guess. Do you have a complete assembly for double Coil, shoe, Support bracket, drum, etc or do I need to purchase each separately? Thanks
