Partially right on this one Phil! I stronlgly suspect that I had these
codes because of 3 broken teeth on the dist gear...it did still turn and
this is why I had eliminated this possibility before removing it...

Huh, I did it with the IM in place, took a chisel and a large hammer and
first bent then took off the retaining plate, then I removed the "mushroom
bolt"  and finally removed the dist. Tadaaaa! 3 broken teeth as said earlier!

I'll check that later when I find a replacement dist or gear....

Okay, thanks for the info...I knew it was cemented and tried to gently
remove it but to no avail so I'll crush it later!

Thanks again for your help!
