Tnx Jay, that's what I thought with the drain valve, I don't think it would be on the top.

I tried the wheele in the back! They don't fit by 1mm or so and rub on the caliper (scratches paint and wheel doesn't turn), even if I put spacers. I wanted to use them on all 4 so they can get dirty no prob (it's dirty at my mech's shop), but I am now short 2 wheels, so just for the sake of moving the car a bit to gain space for the rad support I put my real rear wheels on.
