i have a 91 Crx Hf and am in the process of looking for a 90-91 si guage cluster, but i haven't figured out how to tell if it is an SI of dx,hf,etc. does anyone know what to look for on an si cluster. certain things that the si has.

I couldnt tell the diff between the ones in my Dx and the ones in my Si both 91's

A different redline

Si and hf have tachs. The only difference between those two is the redline, its at like 6500 on the Si. The dx doesnt have a tach.

The dx does have a tach, as long as it is a CRX guage cluster and not a civic one.

crx dx's have tachs??

Mine does. I don't know if the automatic crx dx has one but my 5 speed dx has one.

My auto crx dx has a tach.

My dx has one. I think its even the same redline as the si.
