Welcome to HS...Glad to have another Civic Owner aboard.
I do believe that is the DX trim model and as for a direct bolt in cluster I would say if no one knows on here ask te junkyard when you call and see if they have those yrs for the car w/ a tach..
If nothing else you could get a smaller aftermarket tach and mount it in a non-evident spot but could be noticed and usd by you the driver.
for suspension get shocks/struts lowering springs/coilovers if you can find them for that yr. a set of rims to help your handling, not to mention te strut tower braces. they will strenghten the sheet metal and hold the car solid in corners for better handling. Front and rear can be a noticable diff.
hoep that might might help you a little more....
