67 cutlass supreme is it different than standard cutlass? trying to find parts and anytime you add supreme draws blanks.. power steering gearbox are the same 66-76 right?? getting ready for 455 drop in . frame was greased up by power steering assy, can I pressure check off car to see if tank or gear box is bad.

 

The Supreme is just a different trim level on the Cutlass line. Ignore any catalogs footnotes that claim such-and-such a part won't fit Supremes. The cars are mechanically and body-wise the same as any other Cutlass from that year.
