I believe that Todd is correct. I have only ever seen "R2", "R11", and "R92"
suffixes on IH parts. The parts manual will generally state when a higher
(later) number part replaces an older one. You will see "can be used to
replace xxxxxxRx" in the description. Also, generally speaking, IH would not
assign a new part number unless the new part would *always* be suitable as a
replacement for the old part. The older parts that were castings often had
only 5 digit part numbers with an "A" or "B" 
signifying revisions, adding to the complexity, and sometimes a much later
revision would be given a 6 digit number. And, of course, Case IH converted
all of their numbers to a later system, making all of our old manuals
obsolete (fortunately the CNH computers have integrated cross-reference
capability).

(Ford operated pretty much the same way, using their own numbering scheme. I
am not familiar with JD/Case/Oliver/MM/Ferguson/etc.)

The problem comes in some of the descriptions that IH engineering used. 
For instance, the instrument panel on the Cub is actually considered the
"rear support" for the hood/tank, not an instrument panel.

I agree that Guy Fay or Jim Becker might be the ones to best address this,
or maybe Ken Updike.
