HELP NEEDED Identifying Brake Spindle - likely from a late 70s Volare

This problem has been discussed on the forum in the A Body Thread; but it seems the brake parts are now crossing generations and MOPAR types.

**But, I seem to have a disc brake spindle ID issue with my 67 Barracuda Notchback.
To say that the previous owner "cobbled" together some things on my Cuda, would be an understatement.
The 67 Cuda was likely originally drum brakes all around.
The previous owner (elderly) and his son did most all the work themselves.; and installed single piston disc calipers up front!
I got some "expert" advice at the Carlisle Nationals; but as yet has not resolved the issue with replacing the brake calipers.
**The current issue is, I have gotten rid of his fat tires and moved the wheels back into the tubs with AM Racing wheels with 3.75 inch backspacing.
AND...I went from his 15 inch wheels to 14 inch wheels. (I did this after a lot of inpout and advice.)
NOW I HAVE SOME CALIPER RUB ON THE PASSENGER SIDE!
The Caliper and mounting bracket parts numbers seem to match a 70-73 Duster.
**But, NONE of the Wilwood low profile conversion kits have caliper mounting holes that match up.

After weeks of confusion in the shop that had fixed my back drum brakes, we are now mistified on the fronts!
So, I reached out to the previuous owner's son about what they put on the front end to convert to disc brakes.
The son says..."The outer and inner tie rods were replaced with 73 duster ones as they need to be the larger ones for disc set up. Also the same for the upper and lower control arms. "And after I asked about the Brake spindles, he said....
"I think they were 73 to 76 era? The only other spindle that I know works is off the F body, Aspen/Volare."


***SO.....I am asking for help in identifying this brake spindle.

Obviously, 3 of the holes in the spindle are for mounting the dust shield.
There are no identifying part numbers on this spindle.
Because we can't identify the actual spindle, we can't even come close to finding a low-profile after market caliper replacement or conversion kit that has a mounting bracket with mounting holes to match!
Had no luck with any of the gyrations of 70-76 Duster that the mounting bracket is supposed to be; according to the mounting bracket and single piston calipers p[art numbers.
The 11 inch rotors are one-piece.
My measurement on the daimeter of the spindle shaft is 1.8 inches.
Pictures follow.
