My understaanding is tha the only Ford manual for a 66 was the Preliminary Shop Manual and that the full set of 66 truck manuals did not unclude the Bronco. Is this wrong? I have a Chiltons 66-73 which is pretty good. and a Ford 67 Bronco manual. I also have a set of 75 Ford Truck Manuals, which I got for my F-100. Between these I usually find the information I need although the early 66's were different (mine was built Aug. 65) and there seem to be a number of differences amongst the early 66's themselves. A lot of this early 66 specific info is pretty hard to find
