Anyway, the cheapest way to do is buy an instrument gauge cluster on eBay and replace it. You can search with the keyword "Acura RL cluster" and you may find a couple of them and can buy it under $100 generally.

Another option, I have a working odometer as an extra. I can sell it at $20 including shipping fee.
