Hey, Mike, know what you mean! Still working on my 4am pot of coffee!
I've been trying to look up info on that mess. Yes, there is a particular one-piece kickdown rod made for using on crossrams, bent to fit 'over' the top of the manifold. Have found a few photos of the rod in place, including the rod guide as part of the throttle cable bracket.
Got my linkage set from Crossram Connections, telling him what I had. That kickdown rod came up, while we were talking, which they do have. Pretty sure I've seen them at other sites, too. Just one of a kind thing, made for the maxi. The one question he had was, wasn't sure if the bottom end length was right for a later 727. Their made for 64 models, and such, my 727 is a 67 model.
I can check that real easy, 64 on the floor, 67 in the car, but doubt any dif on that pivot location.
But, like mentioned, haven't found anything on the rod hookup at the bell crank itself, or a close pic of that end of the rod itself. Could be plain as the nose on my face, lol. Need to get my hands on the rod.
