Lyle,
The pedals are different but it is relatively minor. The basic plate
is the same except that the post '39 is slightly narrower in the leading
edge area of the pivot trunnion and does not have the stop lug. Instead
of the single hole for the clevis, the later one has two for some reason.
The upper hole center is 3/4" forward of the rear edge of the plate and
3/8" down from the top. The lower hole center is 5/8" below the upper and
on a centerline between the upper hole and the trunnion center. Both holes
are 5/16" diameter. The trunnion is 1.250" diameter x 1.350" wide and bored
.812" to accept a 9/16" x 13/16" x 1 3/8" pivot bushing. The trunnion width
includes the thickness of the plate. The trunnion is also stepped and pressed
into the plate and then swagged over to secure it, I could not measure
the step diameter but it appears to be 1".
The measures were taken from my '50 pedal but I think they are all
the same from '40? I can look around tomorrow to see if I have a loaner
that you can copy
