Default 72 GTO speedometer Cable

My 72 GTO 3spd manual had a 2 piece cable when I bought it new. 3 speed sticks didn't have a switch built into the trans to operate the distributor vacuum advance like the 4speeds did. They used a speed sensor between the 2 spedometer cables to operate the advance.
The lower cable on mine would break every 10,000 miles, after 2 times I went to the dealer and bought a 1970 1 piece unit and never had another break.
