Tobz,
You should probably contact Bob Whyms anyway, as I understand he is the importer/distributor for the LN engineeringIMS fix.
Also try the guys at
PR Technology Brookvale. They had a ceramic bearing replacement for the M96 engine when I was there last week. It wasn't the LN one, but may do the same thing.
