Hi everybody,

i want to say the rally pack gauges are 2 1/8" in diameter, but dont quote me on that. mustang steves website has a procedure to build your own rally pack if you are so inclined.

2 5/8" fits best. i made a plate from aluminum and fit the gauges in it then screwed that to the rally pack housing. here is an old thread that i posted with some pics of it:
