Replacement coil balance and pivot/bar and shoe

Image 1 is the broken coil balance. It's a dual coil balance. The detent clip is 3/4 inches wide and 3 inches long. The coil spring is 1/2 inch wide. The sash is 8 lbs. I need.to.replace the coil balances and shoe for the upper sash on both sides. Image 2 shows the lower balance and shoe unbroken for reference.

I also need to replace one of the pivot pims (image provided). Please let me know when replacement parts will work. Thank you.

I see the stamp on the coil spring is 5 which would match the series 190-540. If the coil, the detent clip and bushings seem intact, Will the replacement pivot shoe work with the existing other intact hardware?

Thanks Paul. Very helpful!
