For a new driveshaft: use charts to determine how to take the proper measurements. Take measurements and call with all info such as year make and model of vehicle what type of transmission and rearend is in the vehicle, how the vehicle will be used daily driver or race car, offroader ect. And the measurements.

Modifying a preexisting shaft is basically the same determine the correct way to measure take the measurements and call in

Best way to schedule is to first get your measurements and to just call in, we will only schedule appointments once we have received your measurements or your old driveshaft

Will need to use the charts to determine what type of driveline you have once you do that it will give the areas you need to measure. Most all measurements will use a center to center measurement which refers to the center of the u joint on the end yokes of the drive shaft. here is a link to driveshaft page
