Need help , length from 40 v8 motor mount to trans mount

[Zeke3]

I measured my 1937 frame and I get 40.25” from center of the trans mount hole to the centerline of the engine mount hole (not diagonal). When I measured the engine and water pump (without a gasket) I got 26.875” to the center of the engine mounting hole and the transmission is 13.25” from the mounting surface to the center of the mount slot, so I felt they agreed pretty closely.
