I did talk to Patricks and he told me about the diff/spool case issue, if it is the original the s.n. will end in 370 and will not work with the new gears, it should end in 336 to be able to use the new gear set. You all have given me plenty of great advice, and I guess my dilemma is to go with open drive line or keep it 100% original and keep the torque tube, I have everything i need to go both ways, with the exception of the driveshaft if I use the 56 rear end. I will let you know which way I go as soon as I decide, and once again, thanks for all your help.
