Are all GM 12 bolt rear end covers the same? I'm looking for an original to replace the chrome one that is currently on my '66 SS396.

What will I have to pay for a excellent rust free cover?

Thanks.

All of the passenger car covers are the same, the one for a truck 12 bolt is different. i got a new one from Ground Up.

I think the Camaro has a notch cut out on the top.
