the 66 console is argent silver on the top , if it is wood grain it is a later model....

Well, you're somewhat correct there.

1966-'68 were the silver argent, with the divider line down the center.
'69-'76 used the woodgrain.

AUTOMATIC consoles are the same from '66 through '76, fit wise.

4 SPEED consoles are the same from 1967-'70 (other than the woodgrain issue).

The 1966 4 speed console is by itself, in that it uses the 4 speed top plate with what is later referred to as the AUTOMATIC base.
1967-up used a large cut-out on the side to clear the (wider) 4 speed hump on the later cars. The large cut-out was covered by the ever-impossible to find carpet-fiberboard hump trim piece.

Mark.
