To fit a '72 'Cuda. Mine is okay except the little coil spring on the pivot pin is broken, and of course the (special) pin is bucked on the small end instead of just having a nut; brilliant. I think this lever differs between the years too. I could try it fix it but I dunno
I'm in the same exact situation.
There has to be a way to replace that spring without re-engineering the darn thing.
Luckily, a member here has one I believe to be a match, along with the hood latch/lock assembly.
I'm sure someone here will have a spare to get rid of.
Good luck on your find.
