Replacement Speedometer

[Chickenswarm]

HI. I just bought a used Ice Bear Viking trike with a broken digital speedometer and fuel gauge that is not connected and does not appear to be functional if it was connected. Does anyone have a digital replacement they could recommend? Will any digital speedo work maybe with some minor rewiring?

All I've found are the $150+ replacements and i can't imagine that with all the cheap replacement and upgrade parts out there that there are no other options.
