We had boxes of old bullitins and old mags as well as articles on mopars starting back in 1963.I gave most of the stuff to Jim Kramer and others years ago.I may still have some in the files or in the shop attic.If I ever take a mind to look I will.
With the availability of offset bushings,offset bolts and adjustable A arms the problem is pretty much eliminated.A lot of guys install the later big joint parts from later model mopars also.
I do have an old hand drawing from the Ramchargers showing adding 3/4" to the length of the front of the upper A arm and 1/2" to the back.It also described bending the idler arm and pitman arm down 1/4"/3/8".
I would suggest the aforementioned corrections rather than the cut and weld process.
