I've found a 57 1/2 pumpkin for my pickup I just have to go pick it up. I can finely have an open drive line. How do I go about doing it. Do I pull the axels out a little bit then pull the center chunk out? Then put the new on in and reinstall the axels? I've got a 4 speed open drive line transmission to go in also. What do I look for in getting a drive shaft for it? Just needing to know what to do step by step. Some one also mention having to weld somthing on the rear also. Thanks mark
