Thanks for the feedback - I knew Mid-Fifty and others make the arm for the power steering box but wasn't aware that the manual box arm was available - the splines are different - but I'll look into it. Since I've got access to a lathe and good welder I may just go ahead and make my own arm - I'm pretty sure I can do a good job with it and I don't plan to go off roading with my truck anyway!
