Detroit Speed Steering Shaft Issue

[badazz81z28]

Gents,

I have the DSE second gen Camaro frame and I don't feel safe with the steering. When I first tested it out, the steering coupler on the frame side popped off. I have no idea how that happened as I couldn't just "pop" it back on. I re-installed and tried to get the set screw tight. With the engine bracket that slides over it, its nearly impossible to get a allen wrench in there. A few weeks later towing the car, moving the steering wheel etc...its wobbly again.

How do I safely secure this coupler? Makes me also concerned about the set-screws holding the metal shaft. What is the right way to get this thing secure and safe to operate? Do I replace the allen set screws with bolts?
