No excuses on this one. Not only was the car here in WI it belonged to one of CPXs' customers; I saw it several times. However by that time [early '90s'] it had been restored and painted. No data, no pix.
What I do have is a very bad copy of the shippers' copy. The first line is "SPECIAL PAINT." By the time this car was built [N646xxx VIN] black was an RPO color; it is not listed. The owner had spoken with the original owner and stated it was ordered stripe delete.
What a car! Triple black SS-RS, D80, L78, M22, 4.10s, U17, U79, ZL2. Listed for $4,600, a ton of money back then.
