To the question "...... how many degrees of rotation is typical from the Zero NO LOAD to a normal doors up position?" DMC Joe answered "1/4". I'm sure he meant approximately 90 degrees. At a recent PNDC tech session, we had to chase the threads and replace a bolt for the splined torsion bar retainer. With the door held in the fully-up position, it took about 90 degrees to unload the torsion bar (after removing the splined retainer so that it didn't hit the rear window). We cleaned up the splines, chased the threaded holes, rotated the bar 90 degrees, slid the retainer from the tool to the torsion bar, tightened it up, and were within a spline of perfection. The struts were new. Gary IN2TIME 5612 www.IN2TIME.com www.PNDC.org
