For what it's worth, some 30 years ago, I was having trouble with starting my 300D when it was hot. The local car electric shop put in what he called "high-torque field coils", which he said were merely the field coils from a six volt starter ('55 or earlier). Such starter coils were fairly available back then. But since they were installed, the starter has never failed to spin the old hemi. McTaggart [Non-text portions of this message have been removed]
