hpi RS4 sport 3 Cover Hole Propshaft Tunnel

If the steering bellcrank has been modded in such a way that the hole through the propshaft tunnel no longer is needed, this part can be used to cover the hole, keeping rocks from getting in.
Small debris might be able to get in, but the bottom cover is a bit flexible and also not completely sealed so this will be about the same level of protection.  It might be possible to use hot glue or something to get it even more protected.

 I used double sided tape to keep the cover for the hole between the walls of the bottom cover.
