There are several ways to measure for a driveshaft depending on your vehicle. A rule of thumb for single-section shafts is to install a yoke on the output shaft of the trans and push it in until it bottoms out, then pull it out an inch. Measure from the center of the U-joint cap hole to the flat of the pinion mount. Ours measured 57 inches.
