Still need a battery charger, and with only one day remaining, I will just live with it, no more time for the EV wheel.
The gates poly drive is real quiet and smooth, the air cylinder fit pretty well, and since the wheel is on opposite sides of the hinge point, so the weight is nearly neutral, On the lift side, the cylinder is bottomed out, and is held with about 50 lbs of force.On the down side I have about 75 lbs. I will measure it to be sure. On the down stroke, the wheel drops about 2" below the other rear wheels. I don't think it looks bad from the rear either.
