I spoke with Bouchillon Performance and at their recommendation bought the QA1 Tubular K-Member for clearance. I'm strongly considering ordering the Holley mid-mount accessory kit as part of our fitment tests. The shop I'm working with has a few other A-bodies in pipeline to do Gen 3 swaps. Any additional info that I glean as part of this effort will be shared!
I talk to Randy too. He told me the same thing, which I'm not doing. To go that route could be close to $5000 on top of your build. With some thinking outside the box. It can be done.
