Is it necessary to weld reinforcements in to the car for lifting body from frame or is it solid enough that it wont bend? I have 2 post lift and wondering if i can lift from the rockers? car is sand blasted and there is no holes etc on the floor and so on. Im gonna weld braces to the chassis and but 4link rear and air bags etc so much easier to lift the body off and gonna paint the floor under in the same process also.
