Just a comment on this. I just finished the installation of a sway bar on my 1954 3100. The standard 4" ubolts are a little short you don't get full nut engagement. I had to special order 2 5" ubolts and they worked just fine. I also did mine without the engine installed. It would have probably been easier with the engine installed since the springs would have compressed a little with the weight of the engine. I am exited to see how it handles when I get it all back together maybe later this year.
