Did you remove the clock pod? On my 64, it looks like this:
Underneath the clock pod is a bracket that supports the actuators. This photo is of a dash I'm getting ready to install in my car, so items are loose and look crooked, but they are in decent shape:
The two levers on the left run the wipers (with the cable, as shown) and the washer. Those on the left open and shut the fresh air vents. I have two of these brackets because of the dash project, so you are welcome to one of them. Is this what you need?
Not sure if you can send a private message on this forum, but if so, and this is the part you need, send me your address and I'll ship you the bracket.
