Need help identifying my '31 s/w

[christian]

I'm about to order an interior for my s/w fordor. Need to know exactly what I have for the interior kit. I know I don't have a 160c, but not sure whether mine is a 160a or 160b. It's a Briggs, has cowl lamps, and has the pull rope along the rear of the front seat body. With this in mind, I was thinking 160b, however a friend told me the 160b has a center arm rest on the rear seat, which I do not have.

Any ideas ???
