These are off of a March/April built 1970 Challenger with the rallye hood. I'd recommend sending them to RestoRick for a rebuild.

Wow that's weird! I do believe they were originally paired together, here's a pic of them from a long time ago still in hemi orange paint. I was going to use them myself but at the last minute before my car got painted I had them swapped out for a rebuilt set from a '70 parts car we used to have. So they came back from the painter in a box and I didn't really look at them very closely.
I actually can still make a matched pair with welded up-stops as I do have another single '70 hinge. I could sell the stamped one as a single.
Well that is interesting - according to Resto Rick, March was around the time they made the switch, so that would make sense...
From another popst here:

4. Next variation (approximately 3-31-70), the welded-on up-stop was eliminated and they went with a tab that
was stamped with the base. (Presumably eliminating the welding step).
I would be interested in the single possibly, but that would mean hunting down another to match which may not be so easy.....
I have a drivers bent tab mid 70, and 3 pass welded tab available.
19 count springs.
My early springs that I'm keeping have 24 coils, unless I'm counting wrong.
