It has to be a truck service manual. I don't think any of the car stuff will apply. If it is a truck manual the main difference is the automatic transmission. The '95 has a 47RH and the '96 has a 47RE. The RH has a fly weight governor and the RE has an electronic one. Of course, that means that the Powertrain Control Module (PCM) is different. Most of the other stuff is the same. Both trucks have the P7100 pump so the service manual will be the same for them. The '96 has a stronger pump, but that does not affect what the service manual has to say about them.
