I'm with Tim, I make all my own brackets. Very time consuming but cheap and that is what retirement is all about.
What I don't get in all of this is why, if the axle is set up for a four link, are you putting it back to stock? Frame brackets are not that expensive and quite available. Ballistic Fab, Poly Performance, Artec all make good frame brackets, and it is not labor intensive to mount them. This just doesn't make a whole lot of sense to me.
