59 Apache 38 . I pulled the small door panel off . And I mean small. For access to the window mechanism. So by feel I will tell you what I found. The large 6 inch fan shaped gear is dangling down near the bottom of the door still attached to the control arm. I can fish my arm in and lift it up to the general area it should be. Seems to be an attachment point as in a hole of some kind (maybe threaded) in the regulator body about 5” from the handle. So my question is. Does this fan shaped gear (have a name) how does it attach. Does it attach as I think which is at a pivot point with a bolt . What size and thread count? Also on the other side of the fan by the cut gears. Am I correct to think it just slips underneath and in behind the handle side gear on the handle side ? This is the original as far as I know regulator for a 59 . I tried a few bolts seems to be a 7/16 maybe but unknown thread count that I could find . Thinking fine thread of some kind. That is if it isn’t a rivet. Or am I wrong about everything ? Ha ha thanks for all the help
