Well that's something else for me to worry about since I don't have my car running yet. So what is the main cause of the problem, the short driveshaft? My driveshaft is 34" long not counting the splined parts at each end and it looks like my drive shaft leans down at the back by about 10 degrees with the rear input and the trans tailshaft about parallel to the floor. But my weld-in 8" rear has four bar links so if I have to adjust the angle I can play games with the adjustment nuts on the four bar shafts by about +/- 5 degrees????
