Mountain man, sounds like were neck and neck with this MPI 180 kit. I was looking for a gauge mount as well. Only have the boost gauge for now so not a problem but for two gauges I really liked the cr mount, Rat sled and west coast sleds also have a similar mount. With the mounts you will also need gauge pods which you could get from autometer. The next best thing I saw was a mount you could make yourself. It bolted up behind the stock display and had a gauge above and to each side of the stock display. Kind of looked like mickey mouse ears above the display.
Did you get your clutching figured out. I did the same MPI suggestions and am now worried it will be to much weight. I need more snow to get out and test.
good luck
