Well there really isn't much tweaking IMO. Just have to bend them around the brackets a little bit. Hell mine are strapped down in hidden locations with zip ties. I was able to reuse all my zj brake equipment as well.
The iro stuff is good stuff, it's less expensive but more measuring not a lot though. I got a great deal on my artec kit as it was one of the first runs of the truss. Can't go wrong either way you go IMO
And what were you going to strengthen your front to match, the d35????? If you're talking about matching to the 8.8 you put in, then that could be good. Mine is factory front cv axles but 4.56s to match and Detroit trutrac.
