Are there differences in certain years on these cables? I have a cable from a 80 spyder that does not appear to fit a 77 correctly at the firewall. The 77 was an automatic car, so it just had a rubber plug in the firewall. The 80 cable has a offset plate on the end at the firewall, it has one screw that must secure it. Am I missing something?
Here's a picture of an 80 cable, but I couldn't find anything on the 77
