Spark Plug "disguise"
Came across this and found it interesting. The brass nuts are easy enough to find at Lowe's or Home Depot, but looking around in the plumbing section, I couldn't find anything to easily make the sleeve from.
Anyone ever done this?
8-32 Brass Knurled nuts and a 4mm-0.70 tap to get the nuts to fit a Autolite or Motorcraft Sparkplug.
