I'm going to install a T5 in my 46 (216 bellhousing). I want to pull the torque tube and insert a pumpkin from a newer truck. Now I know that a 55-59 will bolt right up and I can use my original axels, keep the orig. brakes etc. But what about newer trucks, say 60-65. Will any of these work?

Also I think that the 55-59s came stock with a 3.90 rearend. I would like to get something closer to a 3.73 or higher. I want to save my orig. rear axel and just bolt something up. Any suggestions?

Thanks
George
