As long as we're talking 3 bolt throttle bodies, the bolt patterns are the same. The biggest difference is that the 90s MPFI throttle bodies are made to mount pointing up like a carb. So, the cam on the side is clocked wrong for use pointing forward like all the "LS" throttle bodies. If you put the early TB on an LS intake, the throttle cable would have to come up from the bottom.
The IAC valve and TPS sensors are the same between the two types.
