Arlie is correct. I have a left and right NOS and a repop Tony Branda on the left side of my car currently. Someday I will replace the left one with my spare, but I am holding on to them for future use if needed.
I found the two I have on Ebay about 5 years ago. They come up every now and then, but if I was you I would not hold up a car restoration for one. They come off easy and the Branda ones are pretty darn close. Any competent body shop will get them to fit very nice.
