4 Spd driveshaft

Talked to drive shaft shp and they want 2 measurements 1st is with the car on the suspension and the shaft 3/4 " out from bottoming. The second is with the car off the ground and the frame on jackstands (full extension) and again the trans yoke 3/4 out from bottoming. But man it's cold in that garage!! Hoping for a few warm days. Thanks for the reply. I have a used bent driveshaft that I will cut and mount the 2 ends to the trans and yoke for the fitting. It should be around 48.6 to 48.8...
