I have everything except my K-member bolts removed to get my engine out. Right now, the car is sitting on four steel rims and is perfectly flat. Do I need to hook up my cherry picker to the K-member before I remove the bolts? I am assuming I can remove these bolts safely without anything shifting, drop the car down, and lift up the frame? I am concerned about the safety issues involved in removing the K-member bolts while I'm under the car.
