Instrument cluster swap

Hey! First post, I couldn't find anything similar so if there has already been a post about this please link it.

I've got a 1999 Thomas built safe-t-liner with a 5.9 Cummins. Gutted most of the dash including the defroster and parts to make room for more storage...but the instrument cluster barely works and is an ugly mess. I was hoping to swap it all out and add a few gauges to monitor things on the road. Do I have to stick with a Thomas built cluster, or could I go with an after market kit, say for the 5.9 from a Dodge + plus some extra to monitor air lines and such?

If that's possible, how can I swap out something like the odometer without doing anything illegal??

I am hoping you get some suggestions on this. I was thinking of designing my own dash and adding aftermarket gauges and switch’s. Not ready to do this but in the planning stages.

You can legally change the speedo as long as you don't lie about the mileage at time of sale. I bet over 50% of the buses out there have incorrect speedos.
I hope you're not thinking of deleteing the defroster, you'll regret it if you do.

Defroster is required by law. Odometer can be replaced, record mileage reading on old one when removed/swapped. Note mileage reading on replacement if it's not Zero. (Ultimately the goal is to maintain accurate track of the total mileage). Many electronic engine computers also track total mileage and in many cases may be more accurate than the mechanical odometers.

I don't know if your bus uses a computer-controlled dash (like IH uses) or if the gauges simply work independently (like many road tractors do) but that's the route I'd be inclined to take. There are many gauge manufacturers offering many styles, so order the few you like air pressure (either a 2-in-1 or 2 separate for primary/secondary), fuel, coolant temp, oil pressure, speed, and whatever others and build a custom dash plate for them. Don't forget indicators - turn signal, high-beam, low air pressure ...

This thread will probably be worth your time reading. This is an excellent job done and a great reference.
