Note that the top grease fitting on the "dog-bone" link has a 90 degree fitting. Also note the fittings are on opposite sides of the link at either end so they can be reached easily without removing parts from the bike.
My Sabre suffered from a common problem... The pro-link suspension creaked and groaned whenever I compressed and released the rear suspension. Honda used bronze bushings in early Sabres and eventually switched to small needle bearings in 1985 but the 82-84 models are prone to problems with the bearings drying out and seizing. The solution is to disassemble, grease, and reassemble every couple of years.
I figured that as long as I was going to take this stuff apart, I might as well put grease fittings in the linkages so I wouldn't have to go through this tedious procedure again. Here's some pictures of my grease-fitting modification.

The "dog-bone" links appear to be symmetrical but I
carefully marked them when removing so I got them back in in the
same orientation when reassembling. The other linkages definitely
only fit one way so you must keep track of how things come
apart.
I figured, since I took off the passenger-peg brackets anyway,
I'd put a grease fitting on the rear brake pivot as well.
