Need vinal spiral ballance shoe.

Has become VERY hard to either raise or lower. Marked as 550C. Size is 2.272 H 1.250 W and. .555 D. Has cut some plastic strings where shoe brake pressed,but are minor & should not be a problem. In 1994 manufacture home.

is your #15-046 a suitable replacmen? In the photos you can see where the shoe or brake have shaved some strings off the back of channel it rides in.
