You unbolt the third member and torque tube assembly and remove it all as one big piece from the axle housing, and bolt in an open drive third member from a 55-62 truck in its place, then fab or modify a driveshaft to replace the torque tube. Replace or otherwise immobilize the pivoting spring perches, and you're set. That's what I did on my 50, and that's what my friend did on his 29 using a 39 truck housing, which brings me back to wondering how similar the 36 truck and 39 truck housings are, and if it could be an option for you.
There are/have been 3.38 gears available for them, but in my personal experience, as-is the 3.90 works very well with the tire size, overdrive ratio, and inline 6 power band.
I didn't know any of this would be an option. If I can do this with my 36 housing, it's definitely something I would want to do. Thanks for making me aware of this possible option.
I'll try to figure out if it's possible, but if anyone knows whether or not my housing is compatible with the 55-62 third members, please let me know.
