Spaghettidecoder.org...find the TIS for it. I haven't done it, but I'm pretty sure you won't get by with just sticking in the hole it slipped out of. I could be wrong, but kind of doubt it.
You did all that bushing work...seems like you'd sense that there's more to it than this.
If you can't find an answer, come back and I'll see if Bentley has something to say about it. And, btw, you should get Bentley...best part you could buy for your car.
As desperate as this sounds, in comedy, 'likes' and 'views,' 'friends,' and 'retweets' really help. If I've ever helped you, please help me by friending, liking, viewing, and retweeting. It makes others think I have a following...it'll take you a minute or less. If you could, I'd really appreciate it!
