I'm trying to understand which oil dipstick is correct to use for 67 428's.
I know the stock dipstick is C7OE-6750-A with the chrome handle, many people have a C7AE-6750-A, and I somehow ended up with a C8OE-6750-C, which I'm looking to replace.
Now reading over these pages:

Assuming you have a stock oilpan, do people replace 67 model dipsticks according to the TSB? The TSB only references 69-70. Also, how does the windage tray come into play? I know people put those on 67 models too.
