Richard,
I recieved my alternator, it has the right rear case for my car. The pulley has no numbers on it.
My alternator did come with one of the studs bent on the rear and when I straighten it, it broke. So I'll have to take the case apart anyway. Other than that it looks good, I wish he would stamp them it two places, when mounted, you cant see the stamp.
I have another one coming for my 69CJ, we will see how it comes in.
