I would guess they are working on it as they do have swap parts for bolting an 8HP or NAG1 into a Mopar, even if they aren't consistent. There are parts for an 8HP for a B-Body but not an A-Body. But the A-Body has parts for the NAG1, TKX and 727, but not a 46RE even though the Terminator X Max can control it. And no TKX swap parts for the B-Body.
Really don't understand why they don't have T56 swap parts, for either. Just seems like it would have been the first or second swap they would have worked on. But I am biased as that is what I plan to swap with the G3.
