Check out this restored Powerful Purple 1968 Rainbow of Colors fastback Mustang. It is being worked on by Mainly Muscle Cars of Washington. This car was originally sold in the Bozeman, Montana area so it is one of those rare Idaho/Montana 1968 Rainbow of Colors promotional Mustangs. This is also the first good example of this purple paint on a 1968 Rainbow of Colors Mustang. We think it is Ford special order paint WT9083.
