Soffseal made all three w/strip designs. Scott Hayes done a great job of explaining the process. Early design, 91 thru 92 had a 'butt joint' type w/strip mating connection. Running change in late 92 began the angle type connection and 93 into 94 and 95 was the final and best design of a ball and socket type. 'A' pillar w/strip final was the one with the drain hole in the runner when standing over corner.
The tops were made wider by approx. 1.5 inches in late 94 production to help cover the side window w/strips and aid in water leaks.
The Body in Whites were sent over three at a time on a side curtain type covered trailer that would pull alongside the dock at C&C and then put on the Flat Table to be reinforced with eventually I believe just over 100 braces of sorts. Then the top came off.
