drive shaft length running a glide
Many people have a custom driveshaft made for such applications and the driveshaft vendor will tell you what to measure.
There are several ways to measure a driveshaft, here are two:
1. Center of front U-joint to center of rear U-joint.
2. Center of U-joint in differential yoke to rear of transmission housing.
If considering a custom drive shaft, I was very pleased with Shaftmasters in Detroit, which is at most 2 days UPS Ground to you.
