I ordered a new Speedo cable from Ireland Engineering. I ordered a 5 speed cable so when I do the 5 speed swap I will already have the appropriate cable. They have them custom made. The 1976 comes with a 2 piece cable system with a box in the middle. This is a mileage counter for the EGR smog system and the check reactor light on the dash. My EGR system has been removed so no need for the 2 piece cable and the box. The process was fairly straightforward. Get the car up in the air and SAFELY on jack stands. Being under the car freaks me out…so I used a number of jack stands and kept the floor jack under the car as well just in case. Once under the car, I pulled back the metal tabs holding the cable next to the body and was able to pull the broken piece from under the car. The other end inside the car I yanked and it came through the firewall. The new cable snaked down and I put it through the tabs. The end that goes in the transmission I had to wiggle around a bit to get it to fully seat. Once I did that it was lowering the car, and then attaching it to the rear of the instrument cluster. All in all it was about a 30 minute fix and now I’m back to knowing how fast I’m driving! As a bonus the needle on the speedo is nice and smooth, not jerky at all. At some point I may try and remove the EGR counter box altogether but for now it’s still there just not connected to anything.
