Adjustable Rear Upper Control Arms
My LeMans has what I believe to be a driveline vibration above 2500 rpm and more noticeable when going through the gears. It has a Ford 9” rear and my angles are as follows:
trans output shaft 3.3 degrees down
driveshaft 2 degrees down
Pinion 1 degree down
Are the control arms the same length for 64-67 A bodies? Some of the application charts don’t include 1964, only 65-67
