    Dear Eric, I bought some long reach 18 mm plugs when I recast the 7-bolt aluminium heads for the VL. I have two left and they are 3/4 inch from the gasket to the tip of the electrode. They are marked UM6C. They were not cheap but not silly money like originals.

      Unfortunate surgeries ended my career about this time last year (among other common obstacles of life).

      If anybody wants to pick up the ball and run with it, I've plenty of IP to share, but with a dying customer demographic, they would have to be even more foolish than me!
