I believe he was the first Mopar source to sell trick/custom parts in volume to Mopar racers. I use to buy quite a bit from him back then. I don't have any pics, but do have a couple of his old catalogs. That's where I first learned about crank scrapers, modified windage trays and more.

Moparts member "Topside" has an ex-Hamburger team car (Super Stock Duster, I believe) and likely a lot more info on the cars & parts.
