First of all, congratulations !
My only suggestions:
1. If you want a taller screen, get one that'll reach up to chin level and no higher; you want to see over the windshield, not through it; remember, you have no wipers...
2. It may be a good idea to fit extra stop lights in the rear (as I did) à la red indicators, so that when you brake you have THREE little red lights, not just the one.
