After having the normal (rebuilt) starter fall and just miss my head, I have decided to add just one more non-original part to my '70 Elky 454. I am rushing to make the start of HRPT, and can buy one of those lighter, gear reduction, hi-tork starters IN-Stock at my local speed shop. These two models I have to choose from have but ONE of the small wire terminals, and it must be the "S". Will my (well-tuned) Points' car run well, or at all without the R-connection?! I am away from the computer Sat/Sun, so I hope someone is there this afternoon. Thanks either way. Mark.
