Acorn Pivot Shoe

I was able to cut out a but if the track to better expose the pivot. Until I buy a snipper to cut away the rest of the track as shown in your video, I was able to better measure the depth more carefully and I now believe its depth is 12.5mm +/- .5mm, bringing its depth more in the range of 0.472" to 0.511". Since 17/32" is 0.53" we're talking a difference of at most 0.06" inch. Do you think it's safe to order your 15-015? What other options would I have anyway?

I am trying to get out my pivot shoe so I can take an accurate depth measurement and order replacements.

I was able to cut off the vinyl clad but as you can see there is metal behind that which also needs to be cut out so I can remove the pivot shoe . What do you recommend I use to cut out that small metal piece? What kind of tool do I need?

Also, once I install the new pivot shoe, what should I buy so I can have a professional cover over the cutout to make a neat installation? Is there a trim piece you sell, or if not, what exactly should I look to buy. If you can provide a link to something I should consider purchasing that would be great. Thank you.
