Rare M Code 'cuda (?)

My 69 Barracuda Fastback still has its original black vinyl top. I read somewhere that only around 600 fastbacks, were built with vinyl tops in 1969.
But sadly, my car came originally with the lowly 318 2V, which has been replaced with a mildly built 340. In fact, I have replaced the whole drive train.

I love how your car looks! That's really slick with the vinyl top!
