How to find what kits an item is a component of?

This might be an easy question, but we are looking to cleanup and delete a number of outdated legacy items we no longer sell from GP.  Several of these low-priced items are components in a variety of kits.  Is there a way to find out which kits a particular item is a component of so that the items can be removed/replaced from the kits, therefore allowing us to delete the item from GP?

Many of these items are service items, so transaction history has never been tracked, but since they are service items that cannot be discontinued we would prefer to delete them rather than just make them inactive.

Thanks in advance!
