Plus I'm starting to get arthritis ( I'm 64) in my left thumb so it's difficult to grab anything.
I gained a new respect for mechanics old and young that are wrenching every day

Oh boy do I feel your pain….
Doing this on our 95 GMC K1500 5.7 is a PITA. I have learned to place a 2’x3’ piece of 3/4” ply on the top of the engine with a towel so I can lay across the engine to get to those pesky back plugs. My biggest challenge is getting the wire boots off without tearing them, thus causing a complete plug wire replacement. This last go around, two years ago prior to its smog test, I placed numbered stickers on the wires and cap so I knew where everything went at the rear of the engine. I also used some aviation anti seize on the boots and plugs in hopes to eliminate the cooked on issue. I expected to have to repeat it this year since smog is due again and with a current odom of 346,000 miles, I didn’t have confidence of it passing. To my suprise and after a “pre” test, it passed. sowing my “shocked” face. I was even more shocked when I did some pre-planning and inquired about a catalytic converter replacement due to the miles and was unsure where the smog would go. It was replaced in 1999 at the cost of $150.00, in 2023 that cost is now $997.00 WTF?!?!?!?!? I was very happy it passed.
