If the GMC is the same as a 49 Chevy the answer is most likely no. The GM Parts book indicates that the prop shaft support bearing is the same for a 46 - 57 3/4 and 1 ton trucks. I was able to find all of the parts necessary to rebuild the one on my 54'Chevy 3/4 ton. If you find out they are the same and have difficulty finding the parts, pm me and I'll try to help. They may be other options but I do not know what they are.
