Hey Somick, just wanted to point out where/why we differ on this, perhaps...not that I'm right, I'll just tell you what I'm thinking...
I used to also drive our shop's wrecker, and I had manuals that described solid points for lifting/pulling/towing on various types of vehicles, as a general reference.
Many unibody vehicles, particularly imports, you find loops and hooks on the body in the front and rear, but the refernce manuals said these were NEVER to be used for lifting or pulling the vehicle, no matter how convenient they appear to be....they are actually for one purpose, to secure the vehicle from moving (tie-down) during rail or sea transport....and that they are not in load bearing locations on the unibody and distortion or damage to the structure could occur if they are used to pull or lift the entire vehicle.
So I always just stayed clear of them. Of course as you pointed out, the box channels aren't really an accepted load bearing location either...so...
And I also just realized that the pic I found is a RWD vehicle, I might have found a better one for a reference...it's good for illustrating what I was talking about, but not for showing possible forward support points on a FWD car...I'll try to find one that might show some points up front that could be used as well...
