98 to 95 engine/trans swap

[hickz3]

Guys, I have a 1998 I just took off the road due to an extensive amount of rust and replaced it with a 1995 with little to no rust. My problem is I miss the power and feel of the 98 in the 95. I want to swap the engine and trans from the 98 to the 95 but not sure what needs to come with it. I assume the PCM is a must, along with belts, pulleys, etc. But is this as easy as I think, or am I missing something?

The original plan was to take the cab and box off the 95 and put on the 98, but it seems like less work to swap the engine and trans. Both trucks are identical colors so it seemed like a no-brainer at first.
