You'll need to stick with 2R 10 or 11 rear springs. The rear springs for the 2R 5/6 use smaller bushings than the rear springs for the 2R 10/11. Front bushings for both are the smaller size. Have you looked up the part number for the springs you want and contacted Studebaker International to see if NOS ones are available? I was able to get new front springs for my 2R11 from SASCO in the mid 90's.
