Dimensions of running boards

[wingnut]

Hi All,
I have a chance to buy some running boards. The problem is i'm not sure what the dimensions should be for a '31 coupe.
The boards for sale are 443/4 long, and that seems like a trk board. Am I right. Any info is always appreciated.

My 31 truck = 39 1/8" long. (outside)
39 1/2" (inside toward body)

Sounds like 28-29 boards. They are approx 44-1/2" long.
