I installed it on my '54 3100. It's a nice upgrade for the truck it makes it real nice to drive. I think if your wanting to keep the torque tube it's the only way to go. I was able to move my power brake booster back 12 inches to make room for the Saginaw and I put the access panel for the Master Cylinder under the seat. I would do it again, if you want to keep original looking. If you want a driver i would probably go with the T-5 and new rear end with an open drivetrain. Overdrive sure would be nice. Just my opinion. If you have any questions let me know I'll try to answer them.
