47-55.1 Steering rod???

The questions are as follows:
First, the u-joints have long screws sticking out of them. I have snugged them up against the rods, but was wondering if I'm supposed to pull it all back apart and drill a hole in the rod for the screws to go in or just tighten up the nut on the screw.

Second, if you look closely you can see where I've got a small green c-clamp holding a "bracket" to the side of a motor mount. The steering wheel turns the steering box easily in this alignment even without power, but I was wondering if I can mount the bracket to the side of the motor mount by drilling a couple of holes and adding a couple of bolts, or if that might compromise the motor mount.

Showing my inexperience again I know, but I'm working on it.
