power steering box re-seal ?

Lookup my post w/ photos. You can get the kits on rockauto <$20. Edleman is one brand. 1973+ gears are different (larger sector shaft) and the same gear as all years of B,C, & E bodies.

You probably know that you will need a shorter steering column. Many here would trade you even or even pay you, since more change to manual steering to fit headers.
