Hey everybody, I'm looking for a local DSM'er to give me a hand with some tasks I've got ahead of me. I've really been treating this old car good as it was left sitting for a few years and needed lots of love. I've got a leaking transfer case on my 1990 GSX and could use a hand at replacing the...

I noticed one of the bolts going into my transfercase was broken off. Is this a problem or going to be in the future?
