Where to find replacement glass for a truck cap/camper top?

I have a Century truck cap that came off of a '94 Mazda B4000 pickup. We bought the pickup after it had been vandalized, and all the cap windows but the front were smashed. Century does not sell parts or anything directly to the public, they only go through their dealers; I called my local dealer and they basically hinted that it would cost a LOT to get the replacement glass for the 4 side windows and rear window, plus I'd have to drag the thing down there so they could look at it and get all the info, and pay them BEFORE I receive any parts, AND they might not even be able to get the glass for it because Century recently changed glass companies and the cap is not new. It sounds like a huge hassle to me, so I'd like to look for new glass elsewhere. Any suggestions on where I could find new glass for this? Would junkyard or pull-a-part be a good place to look, or would they be unlikely to have trucks with caps still on?
