Wheelbase and wheel size of USA 44 tonner motor block

The prototype engines have a 5’ truck wheelbase and are equipped with 33” wheels.
Just wondering if the USA motor truck matches that. I’m thinking that the motor truck might work for powering some 1/24 streetcars.

Wheelbase is 73mm (6’ 11.35" in 1:29). Wheel diameter is 28.7mm (32.77" in 1:29)

Thanks, Dan! That may still work out.

So if my math is good, that’s about a 69” wheelbase with 27” wheels in 1/24 scale.
