I did crawl under the rear last night to get a better look at things. Unfortunately, I have even less room to work with than I thought, so I will have to come up with a more creative solution than what was in my head. The problem with coils in the back of the 60 is the gas tank. It is right behind the center of the axle, so there is barely room for coil buckets, let alone any additional structure.
Check out this thread of
@hoser 's super clean BJ74 build over on Expedition Portal...
BJ74 TD Build Thread - Stoffregen Motorsports - Page 4 - Expedition Portal (link goes to rear suspension portion of the build.) I am going to incorporate some of the same methods, but with the stock links.
Here is my half-cut...
The 60 is roughly 3-4 inches narrower between the frame rails in the rear vs. the 80.
This makes mounting the lower links easy, since the brackets attach directly under the frame.
The buckets will need to move in, as well the lower mounts on the axle by the same amount.
The front structure/upper link mount will get the ends chopped off and welded in the the 60 frame. Shock will mounts stay the same.
The buckets will get the rears chopped/capped to the absolute minimum as in the link above to clear the gas tank...
These will get welded to the frame, just like on the 80 series. I wanted to use a piece of pipe as shown for the rear support, but it doesn't look like I have room. I may just have to tie it between the buckets. We'll see what we can think up.
The panhard mount will be a Ruff Stuff bracket, with the stock panhard bar...
The stock panhard will be shortened using the McMaster Carr adjustable panhard kit...

Fuel line, brake line, and exhaust routing will also need to be tweaked.
