Well gentlemen, the job is complete. It took me 3 hours which is 30 minutes per plug....
It all went well, I took my time.
My body is old and it doesn't like being in weird positions for too long.
I was surprised that the wires came off as easily as they did.
From what I heard here, it should have been tougher.
The part that took me the longest, was fitting the new wires in the harness, routing them correctly, the way the old ones were.
I replaced these AC Delco with NKG copper V power:
The three on the left came from the back...Rusty plugs?
Look at these tips. Did they really make them pointed like this, or have they been worn away this way?
This sleeve was on the back 3 plug wires. What is the purpose of these? I put them on the new wires.
Also, I had a rusty contact on an ignition coil. 5 of them were bright and shiny, but one was rusted, I cleaned it up with steel wool and greased it.
After all of this, it started up better than ever......thank you all for the advice
