Don't use all-thread, it's not very strong. I recommend something like 1//4 inch wall (half inch round I think) metal rod, It can be tapped for threads and then use threaded heim joints for the ends. This will provide strength, adjustability and smooth operation. It will last for years with heavy use and the heim joints can be easily replaced if they should ever wear out. I did this on a manual 67 GMC truck years ago and it worked flawlessly.
