I do have a clock for my gauge cluster but I haven't installed it yet. That spot is empty and I was thinking installing that clock on it. And I have planned on installing tachometer somewhere on my dash, but now I am thinking of installing it on that spot with this one.

Although I have this: Dakota Digital VHX Series Dash on my wishlist, I think it will take time before I can afford it, so this could be solution for meanwhile and it's not too expensive too.
