First off I've never attempted a screw build so I am by no means an expert on the subject.
The part that concerns me, is not so much rivet vs screw, it's the lack of material to screw to.
Especially the front trunnion. IIRC the trunnion is only .100 thick, even with a 32 TPI screw, you're only going to get 3 threads in the trunnion at best. With the swell neck holes probably even less.
The threaded hole must be at least as deep as the diameter of the bolt for proper strength, a 10-32 bolt measures approx .180 in dia.
Back when I was racing NHRA also required that the bolt protrude at least it's diameter from the rear of the nut.
Bottom line, I just don't think there is enough meat there.
I know others have done it, but I just don't like the idea
