Deuce,
The one does indeed say CON 2 (which you knew), the one above the starter bracket says L20 6 and the one just rear of the motor mount is 3877173 with the big GM under it.
I will look again (scrape the paint off) tomorrow as I will be at the garage again. Will I have to pull the dist to see the pad well enough to read it, scrape it clean etc etc?
