I have a 16 1/2" long shifter rod (0.47" diameter) without a 4-digit number that I have been researching without any luck. It appears to be a 3-4 shifter rod and might be for a 1967 or 1968 Camaro, Nova, or Chevelle. As shown in my drawing it has 3 angle points with angles of approximately 165, 168, and 169 degrees.
It might or might not be GM 3895255, 3930053, 3899024, 3930073, 3913714, 3930065, or maybe some other GM part number. It seems the 4-digit stampings started with the 1969 models. I bought the shifter rod at a swap meet decades ago with the 3895244 swivel and 2 3841497 nuts.
