I need to confirm the block and tackle balancers I need for non tilt aluminum windows. The are marked 1920 and 1520. I also need the part that goes on the sash.

Hello!
I recommend either the Series 351 or Series 390 based on what you show here. You'll have to measure as shown below to determine which one. I also recommend the 1920 option for the 20" balance and the 1520 option for the 16" balance.
Let me know if you have any questions!

I don't think mine has the ears at the bottom. 1920 and 1520 is what is imprinted on mine.
I would also like to replace the top sash guide for each window.

My apologies! I meant to upload the image below. I'd be happy to help ID your top sash guide but I'll need to see a photo of it removed from the sash. Specifically, I'd like to see "mugshot" angles of it from the front and side.

I measured the "shoe" on the balancer. I beleive I have the series 390 because it measures 1 1/8 across. It is a bit tricky as the starting and ending point of the measurment are both on rounded edges.
Also see photos attached of the sash guide.
I total I would need:
8 of the 1920's
6 of the 1520's
and 14 sash guides
