I ended up buying an extra Andersen leveler #3604. I clicked the Amazon "one click" button without knowing it, and then I bought a second purchase of (2) levelers. So, I ended up receiving (3) units.
I only need (2)
I got a great price from amazon: $39.91, and before I send it back to them I just wanted to offer it up here.
So, (1) leveler for sale: $39 plus shipping.
