Does anyone make window slide blocks?

The ones in my car look like the ones you posted for the most part. I could have sworn by the weight and stuff that they felt like they were metal though, or at least plastic coated metal maybe? I only thought that since I saw both options listed in the parts manual. I'll have to get them out and look closer next time and maybe try to prod them with a pick ro something to see if they gouge. Right now they are back in the car as there was enough left to give me some amount of retainment, but I'll see about replacing them at some point probably. Maybe I'll have a go at 3D printing some after all, though I need to get my hinges fixed first probably.

I just can't quite get my windows to seal to my new weatherstripping. Pretty much everything is adjusted as far as I can get it, but the window won't go high enough for the top edge to sweep the strip and it doesn't lean in far enough either to touch the face of it either. The door seems to be about as centered as I can get it as well when everything is closed. I know my car is a junkyard mess of parts thrown together until it roughly resembled a vehicle, but just annoying that it's so close, but not enough to seal out the noise. I tried adjusting the weatherstirp track as well, but it's also all the way outboard as much as I can get it, so I'm running out of ideas.
