Definitely check with Dan at Van Steel. Although I think I remember a recent post regarding u-joints where Dan said they are recommending a different brand now because Spicer is using some plastic parts that tend to crack on installation.
The only thing worse than my short-term memory is my long-term memory, so call Dan to get the straight scoop.
If you don't go with him, Look up Local Driveshaft Service in Yellow Pages,Call them an get a price on the joints Spicer Life forged and installations. I learned about this too late and paid $10 each too much. Corvette vendors want 28-32 each, my local shop only wanted 19 for the half-shaft u-joints spicer life and 16 for the drive-shaft. Charged $7.50 per u-joint to install. I wish I had done this to begin with and avoided bending my half-shaft flanges on the press I spent $99 on.
Yes the Spicer life do have an issue with the plastic dust boot seal cracking during installation, the driveshaft shop showed me a half-box full of them, they are okay once you get them installed, and the local shop should have the boots in stock. I asked the local shop which were best the Spicer Life or the Neabco? and they said the spicers were stronger. This shop builds a lot of custom driveshafts for drag cars 8-9 second ETA and says the spicer lifes have never come back.
These joints are used on a lot of 4 x 4 too, replaced them on my 100+k Explorer the other day while I had the tranny out for a clutch replacement. There were still useable but I went ahead and did it while the shafts were out.

Go to a nearby driveshaft shop. If you can't locate one easily ... go to a HEAVY truck repair garage ... ask there ... they'll know. You'll find ujoint & labor prices at driveline shop are reasonable ... PLUS ... if they bend a yoke ... they'll fix it on their dime. If you try and do it yourself you may not have good luck. BTW ... it's spelled Neapco ... a driveline shop'll have spicer & neapco ... DO specify you want ujoints with NO grease/zerk holes.
