Measureing drive shaft

Yes if you have the slip yoke.... BOTTOM it out, then pull it back 1" and measure CENTER to CENTER...

If you are not using that SY or have a SY , then measure from the seal on the trans to the center of joint in the end yoke at the rear.
Then let the shop that is doing it know if the tailshaft is past or before the seal and by how much...

ALL measurements at ride height.... not with the suspension hanging..
