May 1, the Thompson #83 car (MacDonald's car) and Chuck Rodee's #87 are pushed out for some track time. Besides the aero kits, many
other adjustments were made to the cars following the March tests, including major chassis & suspension adjustments all in an effort to
resolve the instability issues. Mickey's rear wing attachment and side skirts were still ruled out by USAC officials. Photo courtesy IMS.
Mickey Thompson's new design was a dramatic departure from the traditional open wheel Indy racer. Thompson was a brilliant innovator
and his aero kit's were far ahead of their time but still unproven on his cars, and at the Brickyard. To date only wind tunnel testing had
been performed and now they were about to find out if the aero kits would successfully counteract the car's lifting and floating caused by
the higher roll center. Dave MacDonald's #83 racer pushed to the pit area and readied for initial testing. Photo Courtesy The Henry Ford

Adding further controversy to Mickey's cars was Colin Chapman's discovery of a radical third-wheel steering arm connected to the right
rear wheel of Mickey's racers. This went completely unnoticed by track officials during car inspections. When this news hit the wires any-
one who wasn't already talking about the Thompson superskates was now. Mickey was a brilliant innovator, and while many of his con-
cepts were revolutionary they didn't always receive proper development time to flesh out potential problems. This was more of an experi-
mental solution Mickey concocted in an attempt to deal with the floating issues. (By all accounts it was disconnected by race time).
May 4 blurb from Motor Trend writer George Moore's "Indy Diary" referencing the third-wheel steering.
Mickey brought in several different nose cone configurations from his Long Beach California speed shop in an effort to find some down-
draft to keep the cars on the track.

May 6 blurb from Motor Trend writer George Moore's "Indy Diary" detailing the Thompson crew attaching air tufts to MacDonald's #83
car. The crew also stationed cameras at several points throughout the track to monitor and film the movement of the tufts. Mickey also
had air vents cut into the front cone and would try various configurations to help improve handling.

On May 9th Dave took the redeye back to Kent WA to run the 5/10/64 USRRC Championships for Carroll Shelby. He raced the King Cobra
to victory, outdueling Jim Hall and his high flying Chaparral - Dave invited Jim to share in the victory lap - this would be Dave's final vic-
tory. While at Kent, Dave confided in his friends that Mickey's Indy car was still not right. Ken Miles, Bob Holbert & chief mechanic Wally
Peat all urged him not to go back to Indy. Carroll Shelby told Dave the car needed much more development and not to run it. Carroll told
Dave he'd build him a better car for the '65 Indy and that he'd even call Mickey for him. Dave told them all that he was "obliged to Mickey
and would not back out and the crew was working hard to sort out the problems and he would fulfill his commitment". Photo Friedman.

Down a racer after Gregory's departure, Mickey Thompson put word out he was looking for an available driver. Bobby Unser brought
young 24 yr old Mario Andretti by the Thompson garage and Mickey immediately offered him the ride. Andretti agreed to come by the
next day and test the car but never showed. Thompson then turned to 15-time Indy 500 competitor Eddie Johnson and invited him to the
team. Johnson accepted and below is his initial run in the #82 car - fender channels and all - and was only able to get the car into the mid
140's. Meanwhile over in the Van Lines camp Masten Gregory was having trouble getting the Offy up to speed. Photo Dave Friedman

engineer told Mickey it would be days, maybe a week before Detroit could send another. Mickey was not allowed to use an engine from

A record payout for the 1964 Indy 500 and race winner AJ Foyt's share was a staggering $153,650. The richest Formula One race in the
world at the time was the 1964 Monaco Grand Prix and race winner Graham Hill's payout was a mere $2,000. It's not hard to understand
why the best drivers in the world flocked to Indy every year.
