Body Mount Question

[axisT6]

In the process of installing Poly body mounts. The large metal washers that go on the bottom of the mount have stamped numbers as follows: A5, B5, A4, etc.... Can anyone tell me which one goes where? I didn't pay attention when I removed them. My truck is a 95 ECSB for reference.
