Need some help with U joints!

[Lowdown89]

Ok guys I'm needing to replace the u joints and carrier bearing in my 01 crew cab 2wd dually can anyone give me part numbers for the u joints and carrier bearing? All the ones I seem to find when searching say 4wd and also there's like 2-3 different carrier bearings listed and I'm not sure how to tell which one I need... I'm looking at the heavy versions if possible
