oil fill relocation tube ?

[mdill]

Hey does any one know the answer to this:
Did GM have a oil fill relocation tube to
allow easier oil access. (I have a 350 with
air in my burban, and it is a ***** to add
oil, long time ago I thought I saw one with
a tube that went from the valve cover over
to somewhere in the area of the brake booster
that had a oil cap on it ?? )


Thanks Mike D.
