A couple of years ago I posted about Blue Moon Motorsports making an IRS for mopars. That's definitely dead as of January of this year. With Heidt finally fixing their IRS to have an upper control arm, that looks to be a possibility, though one with a little bit of fabrication involved.

Does anyone know of any other routes to an independent rear on a classic mopar? I don't care about drag racing at all, so typical "IRS = bad for drag" concerns are moot.
