History on Garnet Red '69 Z28 N515065?

[tom406]

Looking for history on this '69 Z/28 N515065. Garnet Red, black top, black deluxe interior. I first saw it 15 years ago here in Tacoma, WA. Showed a believable 29K on the odo and it still wore most of its original Garnet Red paint and pristine interior. DZ302 out of a slightly later car which was fitted with crossram intake. Also fitted with JL8 brakes and OTC JL8 rearend. Not sure if someone did up a car for themselves or 90's auction but my friend would love some earlier history on how this car survived. Any useful documentation would be great and we can certainly work out compensation.

Thanks!
