did the ones from the FJ55steering that you got from sledge work? Sor.com still shows them still available. try searching, I know this was brought up before.
I've got one still in its original toyota packaging box at home.
I can let you know the part number in about 12 hours time (when I'm home tomorrow morning - Cos I'm at work right now) - if you're still interested then.

The dealer here in Guatemala had it in stock!
Did you only get a spider and a bag of cups? I have a bag of "O" rings and snap rings too. What are the "O" rings for? All the "U" joints I've ever done have seals at the roller bearings, does this one use the "O" rings there instead?
Wow. That's lucky.
No. After taking that photo I noticed another plastic bag I'd overlooked that was still inside the box. It has the O-rings in it and the grease nipple (but I didn't notice the circlips/snaprings although they could have been there too).
The O-rings ARE the grease seals and there are no "needle rollers".
Which makes me remember a very useful WARNING. - Pump the grease into the spider only gently. Normal gun pressure bulges/damages the bronze ends of the bushes!! (Those O-rings seal very tightly - Unlike the seals on ordinary universal joints.)

Is there an instruction sheet in your package? Mine has been on the shelf for years by the looks of it and there is no instructions any longer. I have not opened it so I'm not sure if the installation is clear or not. A "normal" "U" joint is pretty simple but if these are fragile even when pumping in grease I don't want to mess it up.
Maybe someone can scan and post it if they have an instruction sheet.

Hi CruiserGuy
I think the one I've still got was a "spare" I bought when I replaced the ones on my PTO drive.
No they do not come with instructions but they are even simpler to install than standard universal joints (because you have no needle rollers to drop out during assembly).
Each of these joints appear to be designed to be "sealed for life" despite having the grease nipple. So you use grease during assembly and add "just a tiny bit via gentle pressure on the grease gun lever" afterwards.
If you try pumping grease into them like an ordinary U-joint, the ends of the bronze bushes will bulge (as I mentioned before) or you'll pop an O-ring from its seat (with no chance of putting it back in without dismantling the U-joint again).
I've learnt this by bitter experience as you've probably guessed.
But you'll have no problems fitting them and you won't damage them if you take it gently with the grease gun (and don't let anyone else grease them).
PS. Unless you're winching all the time - You would get away with treating them as "don't touch"/"sealed-for-life" after you've fitted them. Steel-on-bronze is a good "bearing" even with minimal lube!

The "Do not let anyone else grease them" is good advice but how do you ensure the Jiffy Lube guys don't go stupid on them? Are plugs available that I could use instead of a grease zerk? I do all my own service except for when I'm travelling and I travel a great distance each year from Central America to Canada and back. I've had Jiffy Lube types who have checked the diff oil level and then put the fill plug on so tight that I needed an impact wrench to get it off!! I've also seen them grease the front knuckles until the grease flows out the felt seal!! Insane, but what do you do when you're travelling?!?!? Those places don't let you watch/advise their "mechanics".
I have had a laugh though when one checked my tranny oil on the '60 when I was 99% sure the seal was blown. He got a shower of hot gear oil after I told him he may want to stand clear
!! I installed my bypass hose afterwards in a rest area.
