67 cuda FB progress UPDATE

I still haven't purchased the passenger side vent glass to replace the broken one that came with the car. I have a question for anyone who is in the know.
Is the vent glass the same for 67, 68 and 69 Fastback barracudas and are the interchangable with any other A-bodies?
Everyone I contact about replacements, tell me "SORRY, NO VENT GLASS FOR A 67 BARRACUDA FASTBACK" I see them on Ebay from time to time but number one, I don't trust them and number 2,m I don't know what side it is. By that, I mean is it a left hand or a right hand? That has always been confusing too me. DO you say it's left hand if looking at the car from the front? Or right hand if your looking at the car from the back? I'm feeling a bit ignorant, but any info would be great.
