do I need new shock absorbers?

If the air shocks are holding air, "that part" of the shock is OK, but do you have a single or twin air filler valve? You used to be able to get them both ways.

HERE's a story for ya:

When I was in the Navy, a kid had a 318 '7x Barracuda, which got nailed in the side. He took it to Tijuana to get it fixed. One day, I was lying on a creeper working on my car, and looked over at his, a "rear view." Looked to me like it wasn't sitting level.

I said something to him, and he says, "Yeah, I know, only quarter we could find was off a 'Cuda which has larger rear wheel cutouts."

So he has a small cutout on one side, and a large one on the other!!!

("Hey, ya only look at one side at a time!!")
