Remove the old gauges as stated above. There are four nuts that hold them onto the dash. You have to remove the gauge pods from each shell. There is a trim ring that is crimped over the lip of the shell. VERY carefully bend the four tabs up(it is readily apparent when looking at back of gauge/shell) and separate the parts. To keep the Dolphin gauges secured in the shell the trim ring has to be re-attached over the front of new gauges and the little tabs bent back over. The shells have to be cut in the back at the 3 O'clock and 9 O'clock positions so that the bracket you mentioned can be attached to the gauges. This draws the gauges in tight. I'll see if I can get a camera behind the dash for some pics and will post them up. It can/will be a bee-eye-itch of a job. Good luck
