Ok, we're gonna have our third and final attempt at doing these dam mudflaps! So, we're gonna jack the reat of the car up with a trolley jack and remove each wheel to fit the flaps. My question, where do we jack the car without buckling the sub frame or crumpling the seems?! Thanks!

The where is as per the manual; the how may involve a shaped pad or wooden block on top of the trolley jack to prevent damage.
