Side sliding window info needed

[WreckITFrank]

My left side slider window has LR etchings in the glass, and the outer frame is a bit different than the right. Can anyone tell me anything about the right side? Would it be easier just to get a new pair to match? I was going to get a rattle kit and clean up the felt, but realized they are 2 different brands and figure why not just get a new set. Thanks.

*sorry, cant seem to get the images to show hosted, so links for now.

Both factory windows. The Pilkington glass one is later/newer

Thanks for the info. Is it safe to assume the newer is a better design? I planned on trying to find a match to the left, or a newer set anyway.

It might be very hard to find a match. You might have to buy two fresh windows and sell off what you have.
