The clevis was there, only the pin and retainer clip weren't installed. Found them in a parts bag the PO gave me. I have found and read some of the online manuals at the OCMP. Sometimes it is better to just have the books though. I bought the owners manual, shop manual, assembly manual and the how to rebuild your Chevy truck manual. These ought to help me along as well as advice from here and the OCMP site. Now I just need to order that front lic. plate bracket and I can hit the road.
