if its anything like the rear caliper pad/dust cover on a 78-80 1000 the side towards wheel should hook first,then snap the outside on B)

For starters put it in a vice to hold it. Nothing like a good holding fixture. Then with the square O-ring in place, put the dust seal into the caliper also. With some clean brake fluid, lube both at the contact area. Then with a small but dull hook tool in one hand and the piston in the other, get the dust seal started around one side of the piston. Then hold that with one finger of the hand that is holding the piston. Then with the Dull hook tool carefully pull the seal out and up onto the rest of the piston.
Now if you are really lucky to have another hand, or person, you could use an air nozzle to add a small amount of air pressure to the caliper body, which will blow the seal around the piston. Like blowing up a ballon.

I GOT EM!

1. slid seal on piston first, but did NOT install in groove, but slid it to the opposite end of the piston as far as possible without falling off(the end of the piston that goes into the cylinder)

2. Inserted the dust cover into the groove all the way around on the caliper with a super small screwdriver. After this was done, I carefully pushed the piston into the caliper until it was all the way in. Then I slid the cover the rest of the way towards the groove in the piston, where it pretty much snapped into place on its own.

3. Brain takes a welcome break.

Next: Do I buy new brake lines? Are 27 yr old ones reliable?

No, the brake lines are way beyond useful life. Ozone and sunlight affect all rubber pieces, that's why tires should be replaced(if not worn out) every 5 years.
