Pivot shoe replacement fit???

A home owner from Florida says:
January 13, 2020
Photos of my old pivot shoes are attached. They are 1/2" deep and 7/8" wide. They appear to be 1-7/8" tall without the broken top metal and plastic. The picture of the one in the channel shows the unbroken shoe.

I was leaning to the 15-167 as a replacement since it is closer to the half inch thickness, but it is 1" wide vs my current 7/8, and the track is exactly 1 inch wide so I'm concerned about the 167 being able to slide up and down.

The 15-179 is better in the width but at 9/16 deep. Si that extra 16th might be a problem because the channel is exactly 9/16 deep.

What do you suggest I do to replace these older shoes?

Hello there! I agree with your assessment. You will probably need to use either our 15-167 or 15-179. Unfortunately, I can't really confirm which one will be best. They both have their pros and cons, which you outlined. I think this is one of those situations where you won't know for sure until you try one. The only thing I can tell you is that we don't have an exact match for your specifications. The two products you picked out appear to be our best options.
