I will double check that, it doesn't seem to be the case, but I haven't given the hinges a real good look.

The spring in the latch broke and I bought a used one off ebay. The mechanism seems to move pretty easily by hand compared to the one on the other side of the car, which is a lot stiffer. If you close the door normally, it will just bounce open. If you do it gently, the first catch will engage, and they you can nudge it to the second catch. Not good for normal use.

I have located a replacement, and on one site it says it fits a 64 Chevelle and 66/67 Lemans/GTO. Another guy who is advertising the Pontiac latch says the part number is different.
