Interesting to see engine mounting bolts going in from below with the nut on top
That's what I thought when I saw it, even mentioned it to Mrs. C. But if you watch carefully, it's not a bolt, but a pin threaded both ends, with recessed nuts.
Sorry about the fuzzy
pictures, TVs don't photograph well.
Just noticed that the fasteners that attach the rod end to the mount tube have the nuts on top!
