I'm installing the full dash cover from MSA on my 78 280z. Everything lines up perfect but it looks like the knobs for trip reset and interior dimmer need to be removed to get it on right. Is there anyway to get the knobs off without removing the dash? I've removed the small plastic panel under the column that is still on in the pics and can't seem to get my hand near where it has to be.

Got them off, they were corroded. Will still have to move the rheostat or trim the cover.
