U-joint grease fittings

[Keith-Baer@idexx.com]

Well, got the engine out of the TR6 and hauled it to Bob Wanta in CT for 
rebuilding/blue-printing.

I'm trying to catch up on various things while the car is engine-less.  I was 
greasing the u-joints and found that I couldn't get my grease gun to snap onto 
the fittings of the rear drive shaft u-joint and the left side u-joint on the 
diff/axle.  It fit on the front u-joint and right side diff/axle OK.  Anybody 
experience this problem?
