The 2-1/16" gauges can be a pain to mount in smaller vehicles - I use the 1-1/2" ones, they fit very neatly into a single DIN space, and can be made to look like a factory install.
I'm away from home right now, but when I get back (in a couple of days) I'll post pics of the gauge install in my Swift, and I'll be doing an install in my Grand Vitara soon, so I'll show you that also.
