Civic Cluster

I have a 92-95 Civic DX, but I just ordered a new cluster because mine didn't have a TACH. The only problem is that It is a Civic SI cluster. If I'm not mistaking, isn't the SI have a b16, thus having a higher redline on the tach. Please correct me if I"m wrong. I'm sure that my lil ol DX should have a redline at about 72k...right?

If there is a difference, can I just put some gauge faces (ie indiglo) that is designed for an EX to display the proper redline.
