Generally i dont like puttin a jack near the suspension arms, u can bend stuff that way... If i remember correctly the crease of the sill runs the length of the car, usually i find u can jack on the crease a bit up from the jacking point if you wanna put an axle stand at the eyelet. Ive used the box section u mention on other cars with no problem, altho i generally jack at the jacking point and then place the axle stand at the box section, i still leave the jack in place generally even tho its resting on the axle stand, its good practice
