Where to buy locking seal for cabover window glass

I replaced all of the rubber seals on my windows earlier this year. I got them from Pelland Enterprises. They have a $4 sample kit that you can order to make sure that you get the correct seal. My MH required 3 different seals to do all of the windows. There is some kind of double-stick tape that holds the window in the frame, but it needs the rubber seal to stop water and air infiltration.
