I'm really glad to hear that they are getting to someone so quickly and ya'll are happy. They really change the look of the engine bay don't they?
When I tried them on Elky's car I didn't notice any reason they would come off. Just make sure they are all the way down.
And I've had mine for 3-4 years and they've never even budged. As the suspension droops, they become almost impossible to remove. Try it the next time you jack the front end up.
