Here are some pics of the fixtures I designed to put my bike on my auto lift. My lift is an Aleco, but the arms on most lifts are similar. You can improvise as needed for your lift.

I used 2" x 3" x 1' channel iron. Used 1 3/8" x 3" bolts that screwed into the arms. I then cut the blocks of wood to rise 1/4" above the iron as to not have metal touching the bike. The channel iron I used is overkill but it is just some I had. I had to make 1/8" thick washers from some pipe because the bolt corners hit the sides of the iron. The big bolt is not necessary either. If the hole on your arm goes all the way through you can use some smaller bolts with some washers and run all the way through the arm. These bolts are not having to bear any of the weight.

I use a C clamp to secure The fixture to the lift adapter and arm. The bike balances fine without doing this but if I'm going to lift it up high I want to be 100% sure theres not an accident. For further security and peace of mind you could put tie down straps on it also.
Nice looking rear end huh?
