I did my wife's 1999 Malibu this way. I had it on jack stands and used an engine hoist. I removed the front engine mount then dropped the motor.
If on jack stands you can use floor jack with a piece of 2x8 on the jack so you don't crack the oil pan.

I used a harmonic balancer like this with a lot shorter bolts. I have a lot of used bolts so I found some that worked.
Be careful as an air conditioner line is close. I also used a seal driver.
Remember to lubricate the seal.
