Default Driveshaft vibration?? 200 4r

My car had a muncie 4 speed in it, still a SBC and 336 rear.....driving around town in any gear the shifter that is mounted on the cross support the stick shift used.....will not vibrate much if any at all....

BUT when up to ~60 mph it's still relatively smooth......get it up to 80+ and doing engine rpm of ~2400 , shifter tends to rattle a fair amount......

what are you guys experiences with this??

Check the driveshaft angle- the trans mount may have given up. I had a vibration on the highway- rolled under the car for a look and saw the rear of the trans was way low. Couple of spacers and some longer bolts, no more shake.
