I recently purchased a L81 that has a trailer hitch installed. I was going to remove it as soon as I got home but have decided to wait when I found out that 916 units were equipped with them from the factory. I need to know if it is original equipment. My local dealer only had a picture from the rear that did not provide any details. I don't have the RPO's availibe to me and understand GM did not keep records at the St. Louis plant. Can some one post pictures of their OE hitch? Iwould also like help in identifying the Gymkhana suspension. Thanks for your help, Chris
