Hi all
A friend of mine sold me a brand new set of UREM37BY plugs to replace my URHM40E plugs. I got them all checked out and installed but when I went to install my ignition leads, they don't fit. The insulatorS of the old plugs sit deeper in the shell than the 37 BYs.

How do I make this work? What parts do I need?
So much for this being an easy swap.
