"4-speed cars with higher performance engines received the Muncie transmission. The speedometer drive was on the passenger side of the transmission. The speedometer cable for Muncie-equipped cars exits the firewall on the right side of the steering column, above and behind the driver's side valve cover just above the throttle rod pivot, and it uses three clips to secure it to the firewall and tunnel. All other transmissions (including the M20 Saginaw) had the speedo cable exit on the left side of the steering column. "
There was also and interesting pic of a bare firewall showing the two locations where the speedo cable passed through. One hole for the Muncie and another hole for all of the otheres.
