The cartrage screws in from the Non-drive side on the Moto and from the drive side on the Trek. The Trek is a 2003 Trek 2000. The adjustable cup on the Moto is on the drive side behind the rings! I found a picture of an intact sticker like the partial sticker on my Moto, it probably is the 888. I deduced this by the colors of the numbers. I thikn the second number I can only see the top of is an 8 and not a 0.
I'm going to pick up some 1/4 inch lose bearings to replace the caged ones. Plenty of good grease and ride it as a 1/6 for a little while and just see what happens.
