Yes. However, you should not have the stock axle ujoints after 20 years. My only point being that it doesn't really matter anymore what came stock because whatever you have has very likely been replaced at least once.

There are greasable and non-greasable ujoints that are available. There are arguments both ways for and against both types. The greasable variety is hollow, and the argument goes that they are weaker than the non-greasable joints because they are hollow. However, the non-greasable joints can dry out and experience that the greasable joints will not have because you can make the greasable variety wet again if you bother to actually grease them.

The grerasable joints can have a zerk at the intersection of the joint, or there can be a zerk on one of the ends, actually built into one of the grease cups.

Thanks for the info. There are no zerk fittings on the front axle shaft ujoints, therefore I can assume they were replaced at some point. btw, did the stock ujoints have the nipple style zerk fittings, or the pin style flush grease fittings? Thanks.

I am not positive on this, but I seem to recall that the axle joints get the zerk fitting in the bearing cup (the type that takes the pin fitting), and the driveshaft joints get the zerks at the intersection. It doesn't really matter though, the zerks at the intersection are protected well, and you can get to them easily if the tire is turned out of the way.
