Asymmetric hoist lift points

Hello all. I am trying to hoist my truck on my brothers assymetric hoist but I'm worried about where to put the arms. I had to back the truck into the garage, then swing in the short arms, then drive forward to get the long arms under. My brother recommended I have the short arms at the back of the truck.

I'm worried I will bend something, and the frame curves up at the back, so I'm lost as to where to put the short arms.. Anyone here have recommendations?

Ida know. I'm only used to using floor jacks. The workshop manual (available on the right side of the home page) shows the recommended lift points for floor jacks. I would assume they would be right for you too.

Thanks a bunch. I'll check it out.
