I can't tell you dimensions but I can say that is is likely too wide for a three wheel cycle such as the Harley Davidson servicar or even the Pashley Enfield Indian single cylinder bullet type three wheeler conversion that was sold in the US under the Indian patrol car name back in the 1950s.

The model T uses tapered axle shafts and straight cut ring & pinion gears. The model T was a 20-horse power set up and many didn't have wheel brakes like the later cars. The rear drum brake set up was for the emergency or parking brake. Actual braking was done in the rear of the transmission. The transmission was a 2-speed planetary unit very unlike any modern systems. The wheels and hubs were integral on early models.
