Tom,
Rex Carson, who ran a speed and dyno shop for many years in Glendale, now lives in Sequim WA. He was a good friend of Barney and may have some history on the project. Although he's not as quick of limb as he once was, his mind is still very sharp. I see him a couple times a year when I go visit family and friends and am planning a trip very soon. I'll ask him about it while I'm there and if he has something to share. He's a bit like Barney was, rather be doing than talking.
