I thought about keeping the parts, but then I remembered I always had buckets of leftover parts from all the cars I've owned, and the owners rarely wanted them. Might as well put them to good use in someone else's hands.Possibly the ugliest car part I've ever removed... I felt like a surgeon taking out a superfluous vestigial organ. At least you aren't asking a huge price like some I've seen for a piece of molded foam rubber.
I have a plastic tote full of removed OEM parts (plus OEM seats) that I am keeping just in case some day the owner wants to restore the car to "original" condition.
