Since my odometer and speedometer no longer work, how does this look for an alternative solution?

Amazon.com

Still need to keep track of miles for oil changes, any thoughts? An external display seems to be the solution

If yall have any other suggestions, please let me know

So have you figured out why they don't work? Common problem is the cable. Less common is the plastic gear that drives the cable.

1990 most likely an electronical speedometer.
Check that the electro/magnetical pickup thingabob at the tail shaft is producing voltage that allows the speedo to function.
Check for broke wires along the way between that thingy and the firewall.
