Goach2 If it was mine would find a drum brake for the open driveshaft system and use it,that way you'll have a great lever brake and modern u-joint system. when you find the drum brake a bolt in drive shaft may be there with it. Also the lever brake will hold a pretty good load because it's working thru the differential gear ratio's. only down side is may need to re-line the drum brake,have been studying that 'cause mine needs it !!
