You can figure this out for yourself by following the steps described in Mark Kramarczyk's white paper.
The first step is to count the teeth on the gear you intend to use. Several others in this thread have observed that the first two gear meshes in the FP gearbox are 32 DP. So if the one you want to use has N teeth, its pitch diameter will be N/32 inch.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
