"John Parsons, who worked at the Hamtramcks Production Department, describes the process involved in building Chryslers newest car line in its oldest plant, starting on its sixth floor. 'Major body framing for each body was done in two vertical fixtures, called 'gates' into which the workers clamped the A-pillar, the inner front fender, the quarter panel, the rocker panel and the roof rail, along with smaller parts. These gates traveled on rails until they were completed, at which point the pairs would be lowered to the fifth floor, where they would be clamped to the appropriate floorpan; the an inner and outer roof would be added and that would complete the uni-body. Ocassionally, the gate fixtures would get out of sync and a 'Challacuda' would be constructed, comprised of a Challenger on one side and a Barracuda on the other. Although the two cars had wheelbases that were 3 inches different, workers usually didn't notice the problem until they tried to weld on the outer roof' "
