90 degrees from the other cross joint and each does the same rocking. The movement should be smooth and no slack where the Cross joint goes into each roller bearing cup. What is the condition of the center bearing and rubber boot, the rubber is usually bad if old and needs replacement. 300 seems high to me for used 2 piece DS that needs some work. I suppose you bought on line and it was delivered so no inspection before a buy? The alignment of the 2 piece is at the center support bearing there are up and down spacers and there are side to side slots. The proper fore aft aliment ti center support is effected by the rear tranny support if that is worn (gets soft and settles ) there will be excessive DS angle. I recommend you replace the rear tranny support if it is old, they can look good but are not. Go with OEM.
