There are two joints shown in the second reference picture. The upper one
shown is the cross and trunion type, which is also used on senior Packards,
and has generally been unavailable for years in the size used by large heavy
cars, which I am guessing is the size used on Imperials also.
The one shown in your first reference page is a normal u-joint, with an
attached companion flange. This does not have a floating length provision,
whereas the cross and trunion type also incorporates a provision for
floating length. You can use either type if they both would fit, assuming
your car has a center support bearing (and I think it does), so that you
don't need the floating length provision in the front part of the
driveshaft.

Well I now understand why I have a u-joint between the tranny and driveshaft
instead of the trunnion thing...
What I don't understand is which one is right.
One driveshaft looks like this:

The other one looks like the bottom picture here:

Anyone know which is correct for a '59? Could they both be correct just
from different production dates?
I haven't been able to find the u-joint from the page07.htm. I have found
the u-joint for the first one but would have to change the parking brake
drum to use that drive shaft. I would prefer to fix the one that should
have been on a '59 to begin with. It might make up for the junkyard
electronic ignition I installed :-)
