Yes, I believe this is correct. The inner bearing is larger on the later ones and so you need the later spindle. This was the basis for the disc-o-tech article using Cordoba parts, or something. Spindle, caliper bracket, caliper, and 11.75 rotor. Too big for 14 wheels.

I found it:https://www.allpar.com/d3/history/mopar/brakes/disc-main.html
Update On Rotors, located a potential source sold by Jegs and Amazon, need to verify fitment. Company call R1 Concepts show a selection or rotor only from OE type to drilled and slotted performance type. Shout out if anyone has used them and found them to be a fit. Thanks all.

Good find if their correct. At first glance I didn't see any measurements? Hopefully the image used is a generic one and not actual and worse case they allow returns. Please keep us updated.

Curious why you wouldn't switch over to the 1-piece rotor?
It's cheaper, safer, and a direct bolt on.

I was really hoping that replacements might be readily available at a decent price, they're not!! I had a new set on the car when I took it off the road in 1976. Unfortunately here in Canada with the salt and sand on the roads and then being in various states of storage the balance weights installed in the vent of the rotors became swollen and distorted the rotor surface beyond use. Other than that they were in very good condition. Lately I have been finding that the rotors I have been buying for my 2500 Ram and also my wife's vehicle are literally rusting out in a very short time. Also none of them are manufactured domestically. I had removed the rotors and checked the bearings etc. on the hubs and all were in great condition (good grease) and also my 3 inch studs were installed in them, so began a hunt for the rotors. I may end up going with new units from Leeds or The Right Stuff, will see where things end up.

Can you elaborate on the safety assertion please? Are you saying this because of the age of said parts or just the fact of them being two parts? Just curious.
Thank you

From what I've read in the past, the main reason they switched was the 2-piece were prone to warping. I also seem to remember pics of a 2-piece that separated during a crash. The hub being on the outside, makes it worse, all the newer stuff has the hub on the inside.
But ignoring the remote possibility of a crash situation, just the economics don't make sense, unless you just want to keep it original.
