Hi everyone, this is my first post here. I just bought a 72 GTO and I am starting the "Little things" fixes. The car is in very good condition, but not a numbers match, just a really nice driver. Transmission is a BW T-10. The original speedo cable is cut off at the firewall. Will a new cable connect to the T-10, or do I need an adapter? How does the cable route under the car to the trans? First of many questions to come.
