1. Looking for replacement balancer shoes for the type shown on my Hurd windows they are 1 1/4" wide. I think maybe
15-195 will do the job although it incorporates the inverted link (swisco #
15-224) into the balancer shoe, rather than as a separate part. Therefore, probably need to replace as a pair (RH & LH) if I use
15-195?
2. I am also missing a couple of the clips shown from the top of the track into which the balancer run. Not sure what purpose they serve and if they are absolutely necessary
