4th gen KL1 lens size?

I did a search and haven't had much luck.

Anyways, I'm looking to get a replacement lens and I found on the sandwich shoppe something I like.

Sapphire Crystal Lens with AR Coating 22.5mm x 1mm **NEW

Is that the right size?

My KL1 is the one with the square beam and a dome lens.


Also, I've been eyeballing the SOB 917 Converter on the shoppe. I emailed them asking if it comes ready to install or if I have to install the resistors (saw the resistor table) myself. I didn't get a replay so I think his spam filter might have stopped my emails.

Thanks in advance.
