A833 Help (what year/model)

626notchback said
I found a 833 on CL and the owner doesnt know what year vehcile they came out of. Is it possible to find out from the casting numbers on the side(s)? any help would be great!

Here are the numbers:
One number is H 3 99129 and the other is H 4 99129

The casting #'s on the side of the case are the same for quite a few years, so the 99129 # doesn't narrow it down too much.

There should be a flat pad above that casting number with some stamped #'s on it, those #'s would tell you what year, vehicle etc.

Do you have any pictures of the 833? Have you identified it for sure as an A-body 833?
