Roll pins are a good choice also. If your'e particularly concerned, then give it a liberal coat of locktite ( green, I think ).

Every DD u-joint I've handled has a single threaded hole in one "ear" with a hardened set screw and lock nut and instructions to get the shaft in position, centerpunch a dimple in the shaft through the threaded hole, and then to carefully drill a slight recess on the shaft to provide a pocket for the set screw to seat, locking the shaft in place. A roll pin needs a properly sized hole through both "ears" of the u-joint and the shaft, right? Are you suggesting drilling through the other set of "ears", which would be through the rounded side of the DD shaft, using the provided set screw/lock nut on the flat side PLUS a roll pin; or are you suggesting using a roll pin large enough to fit a hole drilling out the OEM threads and going through to the other side? I'm not criticizing, but trying to understand what you're suggesting?

Again, I cannot see any reason to go beyond what Borgeson, Flaming River, IdidIt, Unisteer and others provide as their standard offering proven in years of operation. If you're paranoid about the set screw and lock nut coming loose use a round shaft u-joint and weld them. Just my $0.02.

OK Rodger, The second picture was deleted above. Going into edit mode did not provide a path to Advanced mode but I was able to carefully remove the first ATTACH[ ] part of the picture and it worked. I am not a youngster anymore and i have had time to accumulate a few cases where I either over tightened a bolt or did not tighten it enough and now have a healthy respect for a torque wrench. I still have not found the series of comments with Tech1 back around 2006 when I was installing the steering column but he pronounced the through bolt "good" and that was comforting enough for me. Fortunately I do not have any clearance issue with either side of the bolt on the shaft of both U-joints. Over the course of construction of my roadster I also gained a respect for the newer lock nuts compared to the old helical lock washers.
