Im just going through the install myself now. I got a blank dash to clean up the entire thing. I cant remember if it was included in the price or not but you need a bezel to fasten the entire thing. The bezel comes from Docs kustomz.
The unit itself is basically a modern version of what we have in the Bronco. They come in quite a few colors also.
In the box you get all the sensors etc with it. Im also installing the 23g BCB tank and its easy for me to instal the sending unit for the fuel gauge. I could imagine that it would be a pain to have to do it. That being said, you might want to call chuck and see if the stock sending unit is compatible with this cluster.
While doing the test fit everything went in without any fitment issues. Its a great quality set. Now my dash is getting painted. Hopefully I will have it sometime next week.
Hope this helps.
