What size bolt is the subframe bolts?
 

I can't seem to find the bolts for the subframe, what is the correct size and pitch for the bolts that hold up the subframe and diff up?

This is not ment to be rude but check the archive, there is a thread there about subframe bolt stuff. I have never read the thread as I have not had the issue but it might help ya.
