Little bit of digging and I found a grubby little yellow post-it with Rockford 430-10. They made them for nissan, subaru and many other models. They should fit and cost here in NL €29.50 each.

Cup diameter: 22mm

Distance between circlip outer edges: 35.7mm (standard circlips)

@wheee! Mark, If your uni's are stuffed, can you dismantle one and take some accurate measurements?

I have some other part numbers with slightly wider/narrower dimensions.

MSA has them for $299.  With replaceable joints.  They must have a shop that makes them up.   I looked yesterday, it's on page 2 of the search results.  From what I've read about replacements shafts some of them come without the dirt shield and leave the slip yoke exposed.  Something to be aware of.

Other issues besides just getting the old joints out and the new ones in, with either of the possible methods for keeping them in, are balancing.  By the time it's a done, it's still just a part you can't see, that could end up causing vibration problems.  Seems like a high risk-reward ratio to try it yourself.  

I will press out the old u joints and take some measurements. It looks like the 430-10 Rockwell's are the ones I see listed as fitting. (according to Rockwell)

Nice work. I had a list with yhe 720 pick up and as far as I could tell, the 720 had the same staked uni-joints.

Would be good to have an alternative.

They write like replacing a staked-in joint is a common thing.  I have seen kits for other brands of cars, that come with a little grinding/cutting tool that cuts out the stake.  But if I recall correctly the yokes for those kits had a groove already in place, that was used for a circlip afterward.  Kind of like the manufacturer staked in a clipped u-joint for some reason.  Cut out the stakes and use the old clips.

Looks like a fun project anyway.

Found the kit.  You can see the groove in his pictures.  https://www.f150forum.com/f72/replacing-staked-u-joints-175529/

Who knows, maybe Nissan ground the flats on the inside of the yoke for an internal clip, but then staked it in. Can't tell what kind of clips the 43-010 uses.

 

Not to clutter but I thought this document was interesting.  It mentions the crimping.  I searched the number on the end of your u-joint.

Do the grooves match your yokes?

Stalking...

Will have to check when I am home again... darn day job in the way again!

I won't have the bearings for awhile yet anyways. I will press out the old one regardless and get pics etc.

Just remembered some funny fit business with CV axles, from the past.  When I did a Google on it I found that it's actually gotten worse.  Used to be just a specialty axle house, now it's Autozone.

Here’s some shots of the separated joint.
