If its a 67 non a/c...

Matt, you're awesome! My only real problem is removing the nuts that hold the case together. Are they 5/16"? Because my 5/16 wrench won't fit, but 3/8 is way too big. Maybe I just need to try a ratchet with a thinner wall.

Definitely, my preference is to keep what is already there. First, because it doesn't contain any "chinesium" and second, because the only real problem with it is cosmetic.
