There is no easy way know  what you're asking, except a lot of experience
dealing with the components.  There are some lists on the FAQ's that
translate some of the IH Codes into the actual manufacturer and model for
some components, but they're probably mostly Scout components. You can
always ask the Digest and someone will probably know.  One big thing to
be wary of is whether someone is referring to an IH code or the
manufacturer's code.  For example, the T-19 Dan is referring to is a
Warner Gear code.  IH would have called it a T-427 or T-428 on the
lineset.  You will not find the identity of the manufacturer on the
lineset.  Most big truck components are are identified by
manufacturer--Fuller transmissions, Cummins engines, etc., but never, or
very rarely, have I seen a light-duty component identified by
manufacturer, which makes knowing who made what more difficult.

I'm not sure what axles your 65 would have had.  IH pickups used IH axles
earlier and were switching to Dana axles, probably a Model 44 on a 1100,
about this time.  I'd expect the front axle to be a Dana.  What are the
codes on your lineset?  The T-15 transmission is an IH-built unit and I
think the transfer case may be a New Process, that's all I know of in the
pickups.

To set the record straight on a couple of other items:The Dana 30 front
axle did come with disc brakes in '74, although the sales literature
doesn't show this.  I owned one.  The Dana 20 transfer case was
identified as the TC-145 by IH.  The single speed was the TC-143 and the
Dana 300 was the TC-146. The earlier Dana 18 was the TC-144.  I think the
New Process cases were the TC-141 and TC-142.
