Thank you, LadyBee, this should be of help to folks unsure what part numbers to purchase.

 

I made my own gromets with syran wrap and silicone caulk. poke syran wrap into the hole and lay it out on the outside and fill up the hole and a good amount outside as well, cover the mounting stud with syran wrap and spread out as well to protect other areas and ease removal when dry. Set your box in place and leave alone til the next day. Pop it off and remove excess plastic, shape silicone and pop back into place. Pretty simple to do.

 

This is about the LS/LT airbox.
