Not the best picture in the world but the best I could do.Had a similar problem in my '39 p/u with an 8ba mated to the original '39 3 speed using a Merc (or truck) 1/2 bell housing. Turns out the PO had used the starter plated from a car (full bell housing) instead of the correct starter plate for a 1/2 bell application. The car plate places the starter on a slight angle whereas the correct plate mounts the starter perpendicular to the plate. There is an excellent article with photos about this issue. I have it on my computer but can't post it. I'll keep trying.
