the thing broke and now I can see inside of the space.....its really hard to explain it better so, where do they sell this little piece of thin plastic? how do I fix it since I can see the inside...thanks in advanceThe cover on the thing to change gears broke!!?
Id place a guess that the cover kind of snaps in place and if so you can just raise it up enough to put a dot of superglue on the inside edge and fush it up to contact. hold for a few seconds and it should do ok.The cover on the thing to change gears broke!!?
you would have to get it from a junk yard or somewhere online...and have someone do it for you..... or if your not worried about how it looks..just ghetto rig something..like i usually do
