Is there more than one power steering box for a '68 nova? I have a PS box from a '68 but when I bolt it to my frame there is a fight with the exhaust manifold. (Camero ram horns) LT1 manifolds miss by 1/8" Maybe a little close for comfort. A manual box misses the ram horns by 3/8" but I'm getting old and lazy.

Any words of wisdom?
