No. The subframes aren't "interchangeable". MAYBE, with some fairly extensive "rework" of both the body and subframe, but it seems like a LOT of work. But the steering box, stabilizer and brakes would make the effort well worth it. More choices for headers, too.
We did manage a '66 GTO some time back, with a '77 T/A subframe "spliced" into the original frame. A different "job", though, as the GTO has a full frame.
