Old order
Thanks for reaching out! Your channel balance appears to be the discontinued Series 850, cross-bow style balance with a T-Lock Shoe. The good news is that your balance can be replaced with the S795-30 Channel Balance along with the 15-194 1" T-Lock Shoe, which are sold separately. The replacements will come assembled with the 15-195 shoe, so you'll need to purchase the 1" shoes and swap them out.
To determine the exact stamp option you need, you'll need to obtain the exact weight of your sash. There is a chart below the product description that lists the weight range each stamp option can support.
In regard to the tilt pin, I believe you may be referring to the pivot bar. The pivot bar typically used with our T-Lock balance shoes isthe 26-021 2-1/2" Pivot Bar. To determine if this will be a fit for your window, you'll need to carefully look over the dimensions below.
You'll want to confirm the type of top attachment on the balance and how it installs to the window. If your existing channel uses a screw tab, the replacements will work as is; however, if it is a hook, you'll need to check the shape of the installation hole. If the shape of the hole is square in shape, you may be able to use the 26-200 Balance Screw Plug. These will need to be a custom assembly if you cannot use the screw plug.
