The tach cluster swap is easy for the most part.
Some non tach clusters have a ring on the back of the cluster where the speedo cable plugs in and clips into it. The tach cluster I put in my truck did not have that ring to clip into,so I had to fiddle around and slide the cable into the hole and make sure it didn't come out.
You also need to move the speedo cable over to the left by rerouting it through the metal piece that it comes through that looks like a triangle. There's a black flap of rubber to the left and another hole on the side. Route it through that,but don't pull too hard.
Might also help to unclip the cable on the fender well in the engine bay to give you a little more slack.
