Glovebox door spring Early A ??

Hey part 2:
So as luck would have it, my pic a part had a 65 dart that was picked real good, but I found 1 hinge and spring for the glovebox. Got it home, and although I knew the hinge was marked "r" for rightside, I didnt realize that the spring is only for the right??? So what are my chances of finding someone willing to trade me a Left spring for my right spring???

Also has anyone determined that there should be a left spring to begin with? Or did my 66 dart only ever have 1 lonely spring? The left hinge certainly has the holes for the spring
