parts interchange versus swap

[hucklefish]

In the middle of trying to figure out my options for upgrading or rebuilding the brakes on my 520, I found this: http://www.bluehandsvideo.com/uploads/4/4/3/5/4435437/datsun_interchange_1966-78.pdf

I think I understand how this manual works, but could somebody correct me if I've got this wrong?

 

On page 18 (520 index), for '66-69 front brake assembly, it says 304.

 

On page 40 under "304 FRONT BRAKE ASSY" I see parts numbers for RH and LH assemblies and the years and models these part numbers were used in ('66-69 520 and '69-72 521)

 

From this I gather that I can use a front brake assembly for a 521 interchangeably with my original one, and I assume therefore that parts of that assembly are generally interchangeable as well, with some variations. The carpartsmanual diagrams show 3 part numbers for the '65-72 520/521 RH front brake assembly, so this seems to confirm that. Since carpartsmanual lists both a 3/4" and a 13/16" cylinder and the inerchange manual only lists 3/4", I assume I just have to know what part I have before I order.

 

This wasn't a great example, because carpartsmanual combines the 520 and 521 brake parts. But scanning randomly, I find that "1126 HEATER CORE" was used in the '66-67 411 as well as the '66-72 520/521:

 

 

Comparing carpartsmanual diagrams confirms they share the same part number, at least up until 9/68:

  AND  

So I should be able to swap a 411 heater core for my 520 heater core. Did I do that right?

 

Next question, in the interchange manual, does anybody know what notes like these are referring to? Who has/provides "our #972"

 

Third question - interchange means equivalent or identical parts, right? Not necessarily just parts that fit either model. Has anybody ever tried compiling a list of parts that can be swapped in a broader sense, as in they fit but may not be equivalent or identical?

 

Thanks
