Smartball dimensions

[Yakkers]

I'm looking into making a smartball machine in Visual Pinball X, and I'd ideally like to get the dimensions a bit more accurate than I would just by eyeballing it. I wasn't able to find any info online and the machines are pretty rare so I'm not sure how many people here have them or know enough about them, but does anyone have numbers for the general board dimensions and ball diameter? I think if I get those down I can get the physics pretty accurate.

Thanks in advance!

From a very short search. So don't take it as gospel.

Dimensions are 800 x 480 x 220
