add side-open windows?

Anyone know a source?

Heard there used to be one that was primarily an RV company, that is now discontinued on them:
drop-in replacement side windows that pop up on struts
(or half/hybrid would be even better and likely rarer)
in my case to fit a snugtop, on at least one side 05-15

not sure if this is too much of a hassle, regarding even possibility to have it be matching keys
I do have back glass with lock in bottom center, and two keys for it
pretty simple stick key in, go
if it turns into 3 different keys for each window, that'd become PITA...

 

Following because this is something I’m looking into as well.

 

Not sure about snug-top but i was able to replace a sliding window on my leer with a windoor and it was a straight swap, 15 min job. I got the window from my local leer dealer, and the locking cores are numbered so you can match them with what you already have.
