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!
GoldSwinger, If that Holley mid mount front accessory drive with the Alternator, P/S pump and A/C compressor setup would have been available a year earlier I would have bought it and saved myself a bunch of pain!
