pretty darn close there Jon!
On my 1989 premags, oil fill cap is on the drivers side front valve
cover... with the PVC valve behind it in that one... passenger side has
a breather filter which pipes up to the air cleaner fitting.
93 may be different from 89 - but oil fill caps is always on front
drivers side regardless of what year (stock) valve cover.
