Cheers Frank. Good idea. Looking at the Pertronix catalogue, they supply just 2 modules for the 8 cylinder cars, 91884 and 91885. The former is for a dual point dizzy, which mine is not. The latter is for the 1970 600 model, '72 280se,sel,300sec and 350sl, and the '73 450sel. I think there is a good chance that one will fit, but I'd like a definitive answer from Pertronix before I commit.
