Parts for PGT single hung vinyl window 53"wide x 50 5/8 tall

Dear friends,

I am trying to replace all the sash parts pertaining to a 53" wide x 50 5/8 tall PGT vinyl window i have installed in my office (drywall inside, stucco on block outside).

All the parts associated with tilting the window and the balances are shot. The only parts I DONT need are the locking devices and the two clips that hold the top of the sash into the frame.

I DO need:
The 23" balances. They are circular and have a 1/2" diameter - see IMG_0460
The cams that fits into the frame and house the tilt bars and the balances. Each is just shy of 1 1/4" in width and 1/2" in depth - see IMG_0458 and 0459.
One of the tilt bars (broken) that fits into the window and one of the cams is shown in IMG_0449 .

I sure hope you can help me out. My local window guy has a monopoly in the area and that has gotten to his head!!

I feel confident that if I had the parts, I could install them and get the window working again.

Best wishes and THANKS!!
