Howdy Mopar nuts,
Got a 69 dart swinger with 340 and 4-speed. Been having some bad vibrations during acceleration above 3,000 RPM. It gets worse as the engine RPMs go up. Had the driveshaft balanced, made a little difference. I am thinking something is bent in the transmission.
Any help is good help! Thanks
