Subframe bolts

I looked at the torque spec thread and did a search but could not find the answer to this question. Maybe someone can help. What is the torque spec for the top bolts of the subframe? The one I am talking about are the bolts that are hard to get to, the one where you have to move the tank out of the way. It is bolt #19 on the microfiche. Also #25 and #27 are involved. These were a real PITA to get off so I figured they would have some sort of torque amount. If not do I just tighten them as much as I can.
