inverted driveline angles?

[Shotaro]

I ended up with a CV driveshaft from the driveshaft shop in my 67 Chevelle. 80mph on the expressway with no issues.

This shaft cannot be attached to Speed ​​Tech Torque Arms.;(

Is that because of a specific physical interference issue, or?

Why not?

[Mr Nick]

I have a single CV joint at the trans end. Normal U-joint on the pinion end

I went with the same single CV shaft from DSS this year as well. Odd pulsing vibrations on the highway are a thing of the past. The front angle is what it is, which is about 3.5* up. I set the pinion operating angle to 1* down and it's smooth as can be.

Is that because of a specific physical interference issue, or?

yes. "There is no clearance between the torque arm and the shaft."

Your driveshaft is too short.

Your driveshaft is too short.

short? I installed a Detroit Speed ​​leaf spring and changed it to a Speed ​​Tech torque arm. Shafts are the same. And with leaf springs there was no noise or vibration.

You may have multiple problems. The driveshaft is definitely too short and you probably have driveline angle issues as well.

Where can I measure the correct shaft length?

Where can I measure the correct shaft length?

I would push the slip yoke all the way into the transmission, then pull it out .75 to 1 inches, then measure from u-joint center to center.
