Tried the search to no avail: One thing I miss with the Elise dash layout is being able to quickly see oil pre. and engine temps. Really like to be able to get a quick glance when on the track as to what's going on. It would be an ideal location to convert the two center heat/air grills into a mount for oil pre, and a temp guage. I'd imagine I'm not the first to think of this, so am asking for info. Main question is how to remove the rotating air grill without screwing things up, so things can be returned to stock some day. Looks like a small tab inside the plastic bits; how does one release this to open up the air duct? Seems like a great spot to locate a couple of analog guages.. Thanks!
