no markings on part(s)

Question

The only part that NEEDS replacing is the cast metal piece the works the locking shoe. It measures 5/8 "(the outer step; inner step might be 17/32 "). The plastic piece that holds the metal and locking shoe measures 1 1/4" wide, 1/2" thick, and 3/4" high (not next to the spring). I would need two (2) cast metal part replacements. Though, it would be a good idea to order a few more (if one has gone, can the other be far behind0. The window weighs 14.9#.

Hello,

I can't be sure based on a damaged pivot shoe but what I can make out reminds me of the 15-177. Note that this show measures 9/16" deep as shown below. Unfortunately, the metal cams that the pivot bar inserts into is not available separately.

If it's a match, these shows are used with the 1/2" width S152 coil springs. Based on your sash weight, you could use one S152-7 on each side. Thank you!
