actually, it was a standard 1935 Duesenberg SJ that was modified. It had the same 142.5 wheel base, with 19 inch rims.
I couldn't make one and have it street legal here in Michigan though, because according to the on-road vehicle inspection form required to obtain a VIN number, it is required to have 2 headlights if it has 4 wheels. Vehicles with 2 or three wheels are only required to have 1 headlight.

got this info from another web site, so I am assuming it's correct. Also, this must be the current specs, as it says top speed is only 129mph with a straight-8 where with the V12, the 24 hour average speed for the 24 hour record was 153.8 mph.
