In October 2021, I sent my '68 340 FS FB to The Instillation Center for rear quarters and valance panel. I also had US Car Tools Level 2 kit installed. I got the last quarter panels for a '68 before they went to generic single panel for all '67-'69 'Cuda's where you had to cut the panel for the right side marker opening. AMD/Instillation Cty did a great job but the body shop needed to do a little more work to get gaps perfect. Not a big deal.
Photos are of the car blown apart, with panels installed, finder reinforcement, and on rack after painting early in the assembly process. The final shot is with the car nearly complete. All paint and assembly done by Cars Remember When on Dutura in Littleton, CO.
