Haha haven't quite gotten that far yet...so drive means up on jack stands with the transmission (904) in "D". For context, in Neutral and Park, I get the normal amount of vibrations when I give it some gas. A little engine vibration seems normal for the old V8. But when it's in "D" the shakes become much more pronounced. That leads me to think it might be an unbalanced driveshaft. But if you have other thoughts, I'd love to know! All potential diagnoses welcome :)
