C4 Subframe Mounts - PNs and Torques

Would anyone which one of the four bushes is the fixed position bush / bolt, when it come to adjusting the position the subframe relative to the 'chassis' ? Thanks.

There are four subframe mounts. The two front ones are rubber with metal ferules that are pressed into the subframe and two metal and rubber ones that slip into the rear of the subframe and are attached to the chassis via three bolts (per side). All 8 of these bolts are stretch bolts. All of them could be new and just torques (but not stretched) when you take the car in for an alignment. The alignment tech can loosen them to shift the subframe a bit to center and square the subframe to the car. Then they can torque and stretch all 8 bulbs. (See PNs and torque spec in pdf below)
