Yeah, here:

Nema 17 stepper motor mount: https://www.amazon.com/dp/B08DG2JCPY

Heatsinks: mine came with a package of stepper motor dampers that it turns out I don’t actually need. You should be able to find them on Amazon. Look for 40x40 mm and check reviews for the quality of the adhesive backing

M5x30 pan-head bolts: purchased from ebay, or you can try your local hardware store

GT2 belt: https://www.amazon.com/dp/B08R93QQ8Z

Use small zip ties for the end locks on the new belt, or pry the brass compression fittings off the original one and reuse. Zipties are working fine for me. Fold belt over on itself, teeth outward, then zip-tie as tightly as possible.

Y-axis extender: https://www.thingiverse.com/thing:3519404. (Says Ender pro, works fine for Ender 3v2)

You will also need to print a new mount for the y-axis limit switch. There are a bunch of these on thingaverse. You may need addtl hardware to mount it, check the print requirements.

Mine melted because the motor got too hot.

I went with the metal bracket from amazon and 3d printed the switch mount.
