I have a power steering box on my 1988 camaro sport coupe with the number 7819688 cast on it. Is this a box for a third gen camaro? The box was leaking so I bought a replacement from summit Cardone 276550. When I tried to swap the steering boxes today I found that the pitman arm from the original box was smaller than the Pittman arm required for my replacement box. Does this mean I have to get a third gen camaro Pittman arm and all will work right or is the cardone box wrong and my original box (7819688) actually the right one. Thanks.

 

Do they even look the same? Pics?
