Hello Ross
I have a 1990 Plus 4 with the M16 motor also.
Just climbed under this AM and took a pic of the starter.
The label on it reads: Magneti Marelli
Number 26609L 12V
Date 26-89
Type: M79CO.9
Not sure if this helps your situation. I did hear somewhere along that the Rover 820's went to NZ so maybe M16 parts there??
(If you wanted to forward your email, I can send you a copy of the pic).
regards
Colin
