I got mine from Mid-America, but I don't see it in their on-line catalog.
I have that one too. I bought it at Harbor Freight for about half the price. It didn't work for me. I threw it aside after 2 minutes and haven't used it since. The thicker part of the wrench was too bulky too fit in tight spaces. I hope you have better luck with it. I think some have said it was useful on earlier C4's. Not sure. I have headers also and that Ebay wrench with one additional socket works extremely well for me. The extra socket I bought from NAPA in the $3 parts bin in a set of three.

Yeah its a bitch on a GMC Yukon too! Put in a set of Bosch +4 plugs. Truck was so bad it was inoperable. Truly a bad miss. To add insult to injury had to take them out 2 days later and put OEM plugs in and it took me a ton of times.

The snake worked fine for me since May 30, 97. The year does not matter, all C4's #7 spark is a Btcih

#8 is the tough one on LTx cars.

I used a spark plug socket a couple of days ago.After I took a hammer and mashed my hand flat it slipped right in no problem. No seriously the back plug on the passenger side is a little tough but it can be done and the smaller your hands the better.

To some this answer may seem like a joke, but it's not. There is a small access panel that comes off in about two minutes that makes it easy to get to the difficult plug.

It also helps when it's time to replace the plug wire holders/separators, too. Ahhh, the things the almighty Helms manual fails to mention....
