Has anyone noticed that the early fan adjusting bolts (which are 1 3/4) have a domed head? I suspect this was done, to avoid confusion on the assembly line. Comments?
Larry, don't most of the larger engine bolts have domed heads? Dave
I thought domed head bolts were common on the 1926-7 T's ??? But then, they would not have had a fan adjusting bolt located where you are talking about. I've not seen domed head bolts on the '14-15 T's we have.
