Transmission Filler Location on a '73 B

["Dan Ray" <danray@bluegrass.net>]

Quiz time.
All references say that the "early" Bs have the filler/checker under the
carpet, on the tunnel, behind the console and "late" Bs have it on the side
of the gearbox itself.
Is a '73 "early", "late" or somewhere in the middle, hmmm? It's a Mark II,
but before i try to pull up the carpeting on my car and discover no
aforesaid "rubber bung" (???) underneath, I figured I'd ask the question!

TIA
