The '98 DX did not come with a stock tach. I figure I could swap one from a superior model trim onto mine. Could one of you guys with a civic of my generation help me out by posting a dial picture to see if it will fit. I'll figure out all the wiring business later...

 

You can either purchase an EX cluster (96-00) or if you're feeling upto the wiring and fitment you could get an integra cluster and follow THIS link on how to repin your harnesses to use the integra cluster.
