Be careful - on the 4 bolt/old style, the bolt that goes under the trans needs a bunch of washers under the head (if installed from the bottom) in order to prevent it from hitting the trans case. As well as something to keep it from falling out (I used Loctice high strength thread locker).
The next time my subframe is lowered (whenever that might be, maybe for a new clutch), I am going to have the bolts re-installed properly.
