I have two gauge clusters, a 145 5500 redline and a 110 5000 redline. The 145 cluster is inaccrate(oil and h2o). I am going to put in white face gauge inlays on the 110, but i am puting in the 5 speed again and I want the 5500 redline back with the 145 speedo. Can i put the 145 inlay over the 110 and put in a different speedo gear for it to work. Any help would be great.

 

I think you can swap the gauges from one cluster to another. That sounds like an easier solution. Just get all the working ones in the same cluster as the good speedo.
