I have an '05

SSR for which the dealer odered a gauge set. Just came back after spending much of the day there waiting for them to install. The problem is, the set they odered did not come with a bracket for installation or instructions. In checking with a couple different places, they were told by one, the bracket should be with the gauges and the other said bracket was already installed under carpet and padding. Had to cut both to get at bracket. They didn't want to do that until they knew for sure there was a bracket there or get better information on the installation.
Also my '05 does not have an RPO of EGR or EGH. May have wrong set of gauges?
Can anyone help? Don't want to cut carpet unless we know the bracket is there and we have correct set of gauges. Also the number for the temp sensor was not the same on my vehicle as was needed for this set of gauges?
