I went with "Precision" brand u-joints from Napa Auto Parts. They have std and heavy duty versions. Spicer u-joints would have been better, but were substantially more expensive and would have had to be mail-ordered. The Precision joints have a grease hole in the "cross", but come with a plug as well as the grease nipple. I hand-loaded the bearings and body w/ high-temp grease before installation as opposed to using the grease nipple. That way I "know" they are fully lubricated. Precision u-joints have a lifetime warrantee from Napa, so it's convient if I have any issues down-the-road. Warranty covers replacement of the part. Probably a mute point though. I kept the reciept, but it's unlikely they will fail anytime soon. Quality of the new u-joints looks pretty good, (machining & surface finish). We will see how long they last. My existing u-joints were just starting to go, (making a small amount of noise), but no play could be detected "by-hand". Now instead of three distinct "thunks" when the clutch is engaged, all I get is what is probably the play in the differential.
