I don't know enough about 'em to tell you which ones you
need, but I don't think any of the above are correct. My
understanding is that whenever someone references a "prop shaft"
u-joint, they are talking about the joints inside the front
axle themselves; the ones at your steering knuckles which
allow your front wheels to turn and still transmit power;
sort've like what a CV joint does.
Part number 280 sounds more like what you need for the
front driveshaft itself:
PRECISION Part # 280
Front Shaft at Transfer Case, 4WD; Double Cardan Joint; 2 Required
{U Joint - Greaseable Super-Strength}
PRECISION Part # 280
Front Shaft at Front Axle, 4WD {U Joint - Greaseable Super-Strength}
That's just a guess though, not being familiar with what
this particular vehicle needs; you will probably want to get
some confirmation from somebody more informed than I before
placing an order. It sounds to me from the above description
though that the same u-joints are used for the double cardan
joint at the transfer case and the single cardan at the front
axle. There is also a part number 380 for a little more money,
but it appears to be non-greasable, so I'm not sure why it costs
more.
On a related note, you probably know this already, but for
anybody who does not, during the installation, figure out which
way your driveshaft turns while the vehicle is moving forward,
and install the u-joints such that the grease zerks will be
"compressed" by the force from the engine rather than "pulled apart".
