Window balancer

Your window balances can likely be replaced with the S770-29 Channel Balance with a 29B stamp. You'll need to double check that the length of the channel is 29".  Also, be sure to confirm whether the balances screw in at the top of the channel or if they use a clip. Should you find they use a clip, the replacements will need to be custom assemblies.

Your shoe reminds me of the 15-015 Pivot Shoe. Carefully compare the width and thickness of the shoe to determine it is the right fit. If these dimensions are not a match, please confirm your exact dimensions, written out.

For the pivot bar, take a look at the 26-089.
