29' baja is shift cable longer with an imco extension box on the drive
 

replacing my shift cable and am not sure if it is different if I have the standoff box on my lower

Standard Merc lower cable is plenty long enough. I have Stelling Boxes and my engines are moved forward about 18".
The standard lower cable is still long enough with the shifter mechanisms mounted on the engines
Not even sure if anyone makes a longer one..

ok Thank you that's what I figured but wanted to make sure
