Nothing wrong with the U-joints. On my phone screen it looked like a round shaft welded together solid (which could be bad). With the strong U-joint, a DD slip shaft and some solid welds you should be good to go.
In these parts welds aren’t permitted on steering components on street driven vehicles. No exceptions. That said, I understand they are accountable at the race track. Go figure.
I didn’t want any potential hassles so I designed my conversion without any wheels on the steering components. The scab plates are welded to the frame on both sides, but the strength comes from the grade 8 bolts with lock nuts, lock washers, Loctite, and thick wall DOM tubing crush sleeves.
