Clutch Pedal Bushings

My clutch pedal on my 76 280Z has alot of play from side to side and depending on the outside air temp it works super easy when it real cold and stiffens up when its hot. I've had the car since it was new and the best I can remember the pedal worked alot easier when it was new.I recently changed the clutch pressure plate throw out bearing etc. Are those bushings that the pedal pivots on hard to change? They are only $3.00 but it looks awful tight under there. Thanks for any advice.....
