I have a pan anvil that I would like to get finished to work exactly as it should. The one last piece I need is the flat that goes under the anvil to check and align the rear mount arms. I can build the part but don't have the exact measurement of the bolt holes between the frame rails. Anyone here have a factory print of the frame or pan that shows this dimension? I can measure the frames and pans I have here but don't trust them to be correct. Even someone that has an original anvil that would measure the distance would be a great help.
The best source is the blueprint of the crankcase purchased from the Benson Ford library. Or this post mentioned to use a known straight pan to get the dimensions. That may be faster, have a pan checked out on a KRW jig, then use that as the jig checker!
Dan, what I call a pan anvil is actually a KR wilson pan jig. If you or anyone can get me the dimensions for the mounts I would appreciate it.
I sent you a pm.

The bolt holes in the frame for the rear motor mounts should be 21.5" centre to centre.
And according to the Ford drawings John Regan used for his 1909-13 frame drawing: http://www.funprojects.com/pdf/FPIframe.pdf ,
the bolt holes for the rear motor mounts are 30-23/32" from the front edge of the frame.
