More progress. Still needs a bit of trimming before it will sit flat on the frame rails. And based on measurements I have a good hope that the top of the inch plate will sit as high as the top of the factory crossmember. It would be an added bonus, as I would not have to cut and re-weld bracketry.
Cutting the crossmember went too easy, a little over an hour from taking off the grille to taking out the crossmember.
These are the tie-in plates to give it more strength in the are where it joins to the framerail:
Thoughts on it strength-wise?
I noticed the factory us-spec overland hooks are mounted with 10.9 hardware, so that's exactly what I will get for the winch install. And I will have to add some brackets to be able to use the third mounting point for the factory tow hooks.
