Certainteed Pivot Shoe dilemma.
A quick learner from Blaine says:

I have Certainteed DBL Hung Vinyl, sash is 18x24" installed 2003. One pivot shoe is white w/ s170/335 coil and the other is light gray plastic w/336 coil. The installer had a habit of breaking stuff so I'm not surprised one is a replacement. W/O having to remove another pivot and coil I'm wondering which to reorder, as I'm getting extra as spares. Are the lengths the same? Is it just a weight thing? Are 336 a better option? Looks like old style 15-155 pivot and H65 32/3M is stamped on the other thing that holds the spool and coil.
