After a few months had the car out yesterday and a distinct click every time pedal depressed,
so long story short. Looks as if some sort of pad on the clutch pedal has disintegrated and the
cruise clutch switch plastic plunger went into the vacated hole causing the noise.

I did a quick fix and installed a flat head plastic rivet into the hole, but anybody have a picture
of said pad?

 

there are two, B001-43-029 and G030-43-029.
cheap, and very easy

 

As usual, you made it easy, thanks.
As there was blue debris all over the carpet, and the '91 TII rolling shell I have in the
pole shed has the blue piece still in the clutch pedal, G030-43-029 is the one and only $3.17.
Guess I'll purchase two, one for each car.
