I just snagged another set off an 87 Sunday. These had a seperate 1/4" angle/steel piece that "connects" the hooks. It has boxed ends (almost like mini receivers but they're not) with an L shaped bracket that is sandwiched between the hooks and the bracket, held by the hook bolts. Not sure if it's factory....almost looks like a piece of a hidden hitch to me. Somebody else had already been wrenching on the front end before I got there (and donated their 1/4" Craftsman ratchet to me :laugh3: ) so I don't know what all was there, if anything.
I've got some pics of what I'm talking about, just haven't got them posted up yet. D'zat piece sound familiar to you?
