Wayne: well you need to hear from someone w/an ABS model, but I can tell you that on my 1990 non-ABS the right front caliper does not have a bleed nipple, either. There is a metal tube bringing fluid in to that caliper, and next to it is a tube that brings fluid out and up over the front tire to the left caliper. Next to the spot on the left cal. where that "hump" tube goes in is the only bleed nipple for the front.
I bled the front brakes successfully this fall, just bleeding from the one left nipple. But before I did I was on this forum asking pretty much the same question as you...
