I'm a little confused by your question. I'm assuming you mean the trim on the TOP of the console, not the console itself, right?
All 1968 consoles came with a (faux) walnut wood grain shifter plate. If you didn't order the optional U17 gauge package or the optional U35 electric clock, then you also got a (faux) walnut wood grain "filler plate" at the front (see picture attached).
As for the ash tray, read
THIS.
And there's no way to know if your car originally came with gauges unless you have paperwork.
