I will be using the 2 items already mentioned + I bought the frame adapters # 1353274.
They will work out, but if I had to do it again I would make my own since there is so much stuff inbetween the 'frame rails' (support tubes for the impact bumper bolts etc ) that it difficult to drill holes where you need them,+ sway bar mounting bkt. & so on.
One person who placed a review for the 1353274 bkt. said he cut them off at the weld & built from there. At first glance that seems a waste of $ but when you think about the time & material to make something with an adjustable slot etc. it may not be such a bad idea.
