Good find, or no?

Obtained in a parts cache I locked onto. I'm not to front suspension assembly on my 70 RT yet, but since it came with power front disk, I think I should be fist pumping, but not totally sure as I'm no expert. Looking for feedback as to whether I have something OEM here or a couple of good trotline anchors. They're both mic measuring at about 0.990" with little wear if any. Also, recommend ways to restore them.

Yep, those are the original style two-piece rotors.  I've held onto mine as well.   If not for a daily driver, definitely clean them up, have a quick machining to clean up the braking surface, put in some new bearings and you should be good.

Do you have both a left handed and right handed thread rotor?  If so, you are set for the original style set up. (just make sure to warn anyone trying to take off a wheel that was born in the last 20-30 years :-) )

You can media blast them to clean them up.  And get them cut as previously noted, provided you can find anybody with a lathe anymore.
After the media blast you might easily see if you have original studs.  They might be stamped L & R on respective ends, and the the original reverse threaded studs were clad in brass or copper, not sure which but they have a bronzed appearance.

All ten studs are stamped "R", but I may find five that are "L". I love the authentic R/L combo on the 70 models.

I vote for double fist pumps on this one. Looking at those rotors reminds me of a 40+ year old story. I had just bought my 70 challenger , that had 4 bald tires. I had already replaced the passenger side tires, but when I got to the drivers side I found the nuts stuck on the threads. 1st one stud broke, then another. After the 4th stud had broken on the rear axel, some old guy walked past me saying those aren't  "7"s on the end of the studs.

@RJChallenger I have a similar story. I was 18 in 1979 and driving a nice 70 Challenger while working at a body shop that was huge in helping me learn, but a lot of times it came with some good laughs from the "good ol boys" working there with tons of experience and talent. One morning I went out to head for work and found I had a flat. No problem! I've got this! I'm a working man now and living on my own! I soon began struggling to break the lug nuts loose. Soon I gave up, called my boss to tell him I'd be late (and why). He let me know it was no problem. Soon I was calling my mom to give me a ride to work. When she dropped me off, 3 of the good ol boys were waiting at the overhead door...laughing. One said, "well, I guess your mom couldn't break them loose either". (Rolling laughter ensued). Then the head body guy said "if you'd quit driving them f**king foreign cars, you wouldn't be dealing with backwards threads on one side!" (He drove AMC's, go figure). A glance at my laughing boss told me I'd been the joke of the day. When I found a ride home later, I changed out my flat.
