I just found on the search site I need the smaller one. But is there any available? I want to get on a waiting list. How do I do that?

You need the 6080.50. That is for up to 1/2" glass. Any of our dealers can take your info and will call you or email you when they arrive. The 6200.50 you might find in stock but it is definitely overkill.
