Liberty Rear Disk Brakes for A-Body

Mopar Action Oct 2018 issue just came out with the final details of the rear disk brake instillation. Most of the details are straight forward. Need to find a 3/8"-24 to SAE (JIC)3/16" 37° flair fitting. But that should be easy to locate. Jegs/Summit have the fitting in 3/8" to AN3. I need to find out if this is correct. I also want to look into using the factory rubber brake hose vs new lines and fittings. I need to get some hoses to check this out.
MA also has a somewhat hokey emergency brake cable arrangement what I think/hope can be done better. Again, I need to get some junkyard cables and check out a few things to see if there is a neater/cleaner way to do this.
I also want to mock up the brakes to the axle and be sure that the cut they recommend is correct.
I already have a rear proportioning valve on my car so that parts isn't needed.
I have to also check my stud length. I have truck axles that were resplined to the right length for the A-Body housing width. That was done in the early '90's and I don't think those axles are to be found anymore.
So it may take some time to find out what issue I run into, but I will post my experiences when I learn something. Tomorrow I hope to take the 'Cuda to Bandimere for "Test&Tune". I am running OLD BFG Radial T/A's that have no traction, so I don't expect to go better than 14.70's. Altitude at Bandimere also hurts as altitude correction is often 7700 feet +/- a few thousand feed. Now that hurts power!
