intermittent start on 76.

I am hoping someone will have the pateince to help a relative amateur
along here.

I have the dreaded 'intermittent start' issue on my 1976 corvette
(automatic).

I replaced the starter solenoid just to be sure and it started several
times just sitting in the garage, then when I actually went to take it
out, I thought to run the transmission shifter through the gears and
then into park before I took it out to check .... and - no start. I
have moved shifter, etc around since, but still nada. The lights come
on, etc, but the starter relay is not pulling in at all. Battery is
good.

I am suspecting the neutral switch, but it could be the ignition
switch too as they are both the originals (or a wire too, but let's
start with the obvious first...).

From what I have read so far, the neutral switch is under the center
console and it is adjustable wrt the shift lever. It seems to me if I
can get at the thing I should be able to check for voltage running
from the ignition to that switch and out of it to the starter relay.

Can I easily get at that switch by removing the four screws and
lifting that center console cover, and do I correctly understand the
setup?

TIA.
