I have a granny 4 speed that I am going to put in my "59 3100. It has the original 3 speed in it. The 4 speed came out of a "59 3600 and will bolt right up. My problem is that I need a drive shaft now. I need a driveshaft that telescopes in and out. I realize that I am using the wrong terminology but I don't know what they are called. I was wondering if there was a way to find out what vehicles use the right length driveshaft so I could get one at a salvage yard. I was also wanting to know if they make u-joints that are 2 different sizes to adapt the driveshaft if it uses a different size u-joint. I know that I am not the first one to do this so I was hoping I could find out how others have done it.
