You are talking 78-79 magnum right? If so the parts should swap but you will need to run 15" wheels or larger.

make sure you run a dual chamber master cyl. The single chamber will not provide enough flow for disks.

This brings up a question: the write ups that I've seen say to use knuckles from a 73-76 A body or 73-74 E body, and give specific dimensions to go by.

Here's the article I read:
http://www.moparaction.com/Tech/archive/disc-main.html

They state to not use "knuckles from later Mopars, such as 73-up B/R-bodies, F/J/M bodies, etc." with this picture as a reference:

A friend of mine says he uses the taller knuckles all the time, instead of the one's in the article, and never has a problem. This is the set up that he sold me, but others have referred me to the article and advised me not to use the knuckles that he sold me.

Any merit to this?

Those knuckles will be just fine.
