Awesome! So it is just as I thought. Do you know are the '55 1st series axle saddles the same location as the torque tube '53 axle saddles?

Now I guess I just need to decide which one is the better of the two for rebuilding and get to it. I'm going to put one of these under my '53 when I add the T5.

Thanks again for your help!
