Casper lost all 4x4 pieces last month to reduce weight on the front tires. It now runs a 2WD LBZ trans with a 2-pc driveshaft.
The record for A/DT is an open record with a 135mph minimum at El Mirage, and no minimum at Bonneville. There was a 1947 Hudson with a 7.3 Ford engine that ran in A/DT at El Mirage, but he did not hit 135mph. Now the Hudson is in MDT due to some modifications that aren't permitted in DT class. There was supposed to be another A/DT truck showing up at Bonneville, but I'm not sure if they will make it.
