Has anyone successfully used the USCartool A500 Crossmember?

Do the fittings in the A904 come out in the same spots as the 42RH A500? I dont have an A904 to compare anything to. If everythings in the same places on both, I can get fittings from an A904 in the junkyard, and just buy repop lines.
As far as I remember, yes. I'm working with a 46rh and it's the same as the 727.
