It would be pretty simple to figure it out by using the old Pythagorean theorem for right triangles: A2 + B2 = C2. No, I can't represent "squared" properly with this keyboard! You'll need to know the vertical distance the rear end travels, the distance between the transmission output shaft and the rear end flange, and the length of the driveshaft. The driveshaft length will be "C", the hypotneuse of the triangle. As the rear end moves up and down, the shortest distance would be when the transmission output shaft and the pinion flange are at exactly the same level. The driveshaft should be at least an inch shorter than that dimension.
