Top 5 worst A-body repairs/restoration jobs

Removing the clutch pedal over center spring in a car with the pedals installed.
After trying to jam coins, washers, etc. in the extended spring (which didn't work), I had to use a cut off disc in a dremel tool to cut the spring off.
What a pain in the *** even with the driver's seat out.
Next time, it will be done with the pedal assembly removed from the car and done on the bench...........

Another gripe that comes to mind is installing new steering parts like ball joints, steering box, etc. that are supposed to be good to go out of the box only to determine that they are defective.
Then you have to remove, return, and reinstall until you get good ones.
I went through 3 sets of upper and lower ball joints on a car until I went with another brand where they were perfect the first time around.
There were no apologies from the manufacturer either, which REALLY pissed me off!
All I can say is, don't buy Spicer ball joints.........
