What clipless pedals fit with NOS Campagnolo crankset?
Over the winter break, I did a little drafting at an architects office as a temporary. My boss "just happened" to have a pair of Campy Victory crank arms, untouched, flawless, gleaming that are perfect for my Colonago Triopmphe rebuild. It was pretty lucky and he gave me them for free (pretty nice guy, right?)
Now I'm trying to find a pair of clipless pedals to use on them, the threading says 9/16" x 20 F on the inside of the crank arms. I tried a pair of Shimano pedals I had lying around on the cranks and they would not thread. They would catch for a full turn and then stop.
So are these cranks too old to have the common threading that are used on pedals today? If so can someone direct me to pedals that would fit it?

May just need to tap the pedal hole. I've had old cranks give me a hard time with new pedals, but it is the right thread pitch. It's possible that the thread "shape" (different angle and valley) is Italian on your crank, which is just different enough from modern standards to be tight.

Older Campy pedal threading, though standard, is tight. My Nuovo Record cranks were the same way. My Nuovo Record pedals threaded in pretty easily, the Crank Brothers pedals were very tight. Make sure you are not cross threading, but grease them and crank them in. I did that with mine. The Nuovo Record pedals still fit just fine, and any modern pedal I have put in also fit just fine.

Banned.
Though Italian and British pedal threads are both 9/16 X 20, Italian is a tight fit with British. You will do no harm by running a tap through the crank, provided you have the proper taps, know how to use them, and they are sharp. I would rather run a tap through the crank than force a pedal through.

Just to be clear, all 9/16 x 20 pedals should fit if each set of threads is not altered or damaged. Sometimes looking at the threads you will see that the peaks and valleys are more rounded, and some are more triangular. I think this may account for the occasional tight fit of apparently clean threads.
Make sure you are not using tandem threaded with std. thread. Rare but possible, and will not work.

Way back in the 80's when Look and soon after Shimano (who markets Look licensed pedals)… we found that they were tight threading into Campagnolo cranks.
We attributed to that Nationality prejudice.
I would just find a Campagnolo solution.
You got the cranks for free… so you have some budget money for Campagnolo.
Campagnolo even made a Look licensed pedal for a time. After the SGR attempt.

There are some older threads dealing with this. One such:
https://www.bikeforums.net/bicycle-mechanics/899598-non-campagnolo-pedals-campagnolo-cranks-italian-thread-rant.html
Not sure whether Jeff Wills ever tried that or not. Threading the pedal in from the backside was one good suggestion. Having an LBS run a tap through is another.

I had Shimano SPD pedals fit way too tight in NR cranks, so did a back-and-forth installation by reversing the rotation a few hundred times as the pedal advanced into the crankarm.
Better to use a standard pedal tap than to risk cracking the pedal eye of the crankarm imo.

Try a different set of pedals and see if you still have the problem. I purchased a set of Shimano pedals new and they had damaged threads.

I don't know what the deal is with NR cranks. I wanted to try a set of Superbe Pro pedals on my Pinarello that has NR cranks. Couldn't get them to go. I tried a couple of other brands of pedals to see which I liked best without issue. It isn't the Superbe Pro pedals because I tried them along with the other pedals on other cranks without issue.
