Well I have a '55 1st, and since I've replaced the rear axle I have an idea
how its mounted.
I'm not sure why your ubolts are square. Mine are rounded and extend over
the axle and down through a plate that is under the springs. That plate
also mounts the shock.
If I remember right the rubber bumper is on the outside of the frame above
the axle.
Maybe I should note that my knowledge is based on what mine looks like. It
did not have the original axle when I got it, and I've since replaced the
axle because the one that came with it failed.
That very cool spring perch on your '40 is to allow the axle to move
relative to the springs, since the closed driveshaft won't allow it to move
relative to the driveshaft. My '54 has a hinge type mount for the same
purpose.

Subject: [oletrucks] 1955 1st series rear end
List,
I am sitting at home scratching my head a little. I'm sure a shop manual or
something would provide the answers, but I don't have a shop manual for
this.
I am switching my 1940 to open drive and have a 1955 1st series rear end to
replace my 1940. The question I have is how does this rear end attach to the
rear springs? The 1940 has a very cool spring perch that completely
surrounds the axle tube, and has the rubber bump stop held on under the
u-bolt, and the u-bolts run up and over this perch/saddle to hold the axle
in place on the spring.
The 1955 axle has a perch welded to the bottom of the axle tube. Are the
u-bolts only supposed to go up and over this perch? Is that why the 1955
u-bolts are squared off instead of round like the 1940?
On the 1955 is there a rubber bumper on the axle or is it attached to the
frame?
I have the 1940 half ton down to a bare frame. The rebuild starts in the
next week or two.
Thanks,
Bill Schickling
