It's a 1979. I actually met a gentleman at work today, who was having a complete stereo put into his 1979 450SLC 5.0. We were introduced, as the guys at work know that I love seeing all of the cars that they consider "odd". He may have a source for a low mileage 5.0 for me, with 4 speed transmission. I already have the lightwieght bodywork, and if I have to replace the engine, I might as well do it right.
