Are these Model T or Model A Subrails?

[Brent]

Hey fellas! How sharp does your brain feel, today?

Prior to seeing these rails, I had heard they were for a 30/31 A. I need some because my car has none.

A quick look and I knew they weren't. Still, I'd like to know what they are.

The toe area is similar to my T roadster. It has firewall to frame brackets, too. The sill plate is like an A sedan.



So, what exactly am I looking at here?
