So the problem is that I wanted to replace my front suspension but I have no idea wheather I have a 3 or 4 groove pitman arm. Is there anyway to tell by the year of the car or the VIN so that I can just order one and be done with it ? I really don't feel like grounding the car in order to check the part and then wait for who knows how long before they arrive. Mine is a 01.2003 H2. Thanks for any input.

 

Most likely 3 groove. Every one i've worked on so far has been a 3 groover

 

Groovy Thanks for the information.
