I have a 1990 d21 nissan pickup truck and one of my rear universal joints just started going bad. After stopping at autozone and napa I found out that these "staked in" universal joints are hard to find. I did alot of searching on ebay, and the internet and i finally found a good source of replacement universal joints for nissan and other foreign makes. log onto: Staked-In U-Joints
they manufacture these replacement joints and also have a downloadable sheet to show removal and replacement of these u joints. The u joints are less than 25 dollars each. save your self a fortune and check them out. I am posting this as I had several hours of searching invested into this and I am very computer literate. For some part time surfers you might have never found these. I also would like to save someone else some time. As you can see from the cross reference chart on there website my 1990 2 wheel drive d21 4 cyc truck takes a 430-12 style of u joint. happy hunting.
