This is a large single hung window. Moveable sash is 39 x 44. It is a Certain Teed vinyl window made about 1995. It is a spiral balance system. Pictures of the pivot shoes are attached. The dimensions of the pivot shoe are 2 1/8" High, x 1 1/4" wide x 5/8" deep. What pivot shoe part number would i need? Another question I have is how do I remove old pivot shoe without having to buy a $148 spreader? Hope you can help. Thanks.

Check out the video below which details the 'Cutout Method' of removing and replacing a pivot shoe. I think you might find this to be a better alternative--not to mention cost-effective to.

Thanks for the tip on the cutout method of removing pivot shoe. Referring back to my original post and photos, are you able to tell me which pivot shoe is the correct replacement for my window?

Apologies. If the shoe is truly 5/8" thick, then the 15-047 would be correct. I think it's best to remove the shoe to make sure you get a good reading though, as slight differences in that thickness dimension are non-trivial. For instance, a 9/16" thick shoe would indicate you need our 15-121 instead.
