I'm looking for data on 67 Chevelles concerning the speedometer cable hole in the firewall. The 66 model year may also apply.
I have a 67 El Camino that originally came with a Powerglide and the hole in the firewall for the speedometer cable is just below the steering column. Question #1. Would I be correct in assuming the 3-speed manual use the same hole as the Powerglide? I also know (I think) the 4-speed speedometer cable enters the firewall on the passenger side. Question #2. Would (or should) the firewall have provisions for both cable locations? My Fremont-built El Camino (w/PG) does not have a hole on the passenger side. Question #3. Would (or should) a 4-speed car with speedometer cable hole on passenger side have the hole on the driver side and just have it plugged or would it even be present? Then. Where is the hole in your firewall for the speedometer cable? What year? What plant? What factory transmission? Thanks! Dale
