Rotate engine to remove back spark plugs

I need to change the back spark plugs.

According to what I researched thus far, GM states that it is best practice to rotate the engine. While there are videos out there that shows you how to do this, the challenge is however, is finding the correct resources necessary for the specific application for the 2000-2005 model years.

While do I have the Haynes repair manual, and it does have the instruction to connect the ratchet strap to the engine and to the frame or radiator core for support, but it does not the visuals to perform this portion of the operation.

I am respectfully request some form of visual support in the regards to properly strapping and securing the engine of the engine listed above for rotation.

Thanks!
