Heres a great deal on a form S

I like how he says,
"68 Cuda Formla S car is all orignal, not restored. all orignal sheet metal, orignal interior. no rust or bondo, never used in winter. This car has a 70 T/A 340 sixpac motor with around 66k on the enjine."

If it was all original then it would have the numbers matching engine.

O yha and I love his spelling!
