About to do a clutch disc change.  Is there a test/trick to know if the pressure plate needs to be replaced also.   I have a brand new disc on hand.   I want to avoid having to buy a new pressure plate if possible.    The engine is ea82 and the tranny is 5 speed dual range.

Inspect the plate, make sure none of the fingers are bent or broken. Check the mating surface make sure its not pitted or scored. If that's all good then I would say the pressure plate is probably fine.

Make sure to change your piolt bushing and throwout bearing while your there though.
