My power steering box is leaking....everywhere. So I decided to order a new one from Rock Auto. The box arrived today, but it's way smaller than the power steering box that's in the car. Anyone aware of a smaller power steering box? Will it fit in place of the larger box? I sure hope I don't have to send it back for credit. Almost forgot.... car in question is a 1974 Valiant Brougham, V8 (if that matters).
