Subject: Re: More Unknown M45 Parts? And Starter Motor Question
The ribbed aluminium plates look exceedingly like V12 water jacket plates to me!
"M45" on the starter believe it or not, is coincidence, but that doesn't mean it might not be correct for the car. "M" is the Lucas type designation for a starter, & "45" reflects the diameter, 4.5 inches. My LG6 (similar Meadows engine) currently has a non-original M35G starter, but I bought an M45G at an autojumble to replace it, as I don't think the M35G is man enough. If both starters fit the mounting holes for the starter on your engine, I'd guess one is original & another bought as a spare.
