my former A66 car was an early Dec 1969 SBD and still had ( I assume it was original) grill in it, and it was argent. When I bought it that car was mostly un-touched,,and about 70% original paint

Also a local friend of mine used to own a 1970 challenger 340 car many years ago (mid 80's time frame )
I think, it was original paint car ,,,,,, and it had a flat hood. He sold it locally ,and the next owner drove it around here for a while then re-sold it about a year later. But it hasn't been seen since. Seems like the car has vanished from this area so I can't guarentee any of the above.

It was a medium blue( B5 ?) with white interior 340 console auto and the afore mentioned flat hood. Sorry it was a long time ago and before most people cared about fender tag data,,,,don't remember the grille color on that one
