I would not count on a rivet (or even 4 rivets) to do that job. I welded mine, and have no problem sleeping at night. Maybe somebody makes aluminum rod ends, but Wicks only sells steel. My pushrods are 4130, welded to the rod end fittings. I'll bet if you walked into a welding shop and told them you'd like those welded, you'd be done in ten minutes with a charge of "we'll catch up next time". It's hard to imagine sometimes how you'd need much strength in tension or compression for these pushrods, until you find yourself pointed straight at the ground full throttle and have to pull out of a 180 mph dive. A rivet just wouldn't hack it, and even if it would, it would loosen over time and introduce slop, which is not something you'd want in your control system either. Weld it...
