Anybody know the size of the Cotter pin for the pitman arm? This is the last item on my list I need to replace my steering gear box. Thank you in advance!

 

I have a variety of sizes and lengths in my toolbox.
I always use the biggest/largest size available for the drilled out hole.
If not sure and not included with the new unit, pull the new one out of the box and buy it right then at the Auto Parts store.
Lots of torque here, no under sizing to be safe!

 

3mm x 30mm

1/8" x 1"

 

I appreciate it fellas! It never occurred to me to check the packaging with gear box...doh!
