Got it, thanks. I'll get the "earlier" dryer from Polar Bear, then. Will report back!
My best luck has always been to take the piece to an A/C supplier if you have one local. Set it on the counter and say that's what you need. An experienced guy can usually come up with something pretty quick.
If you're buying one sight unseen, it might be wise to confirm that the in/out connections and the connection for the pressure switch are the right configuration and in the right places, otherwise it'll make rerouting your hoses more difficult. Probably best if you send the supplier a pic of the old drier & connections - that or do as Brian says and just find yourself a knowledgeable local supplier and bring the old one to him.
