your best bet is to look up the local Pull-a-part in your area for it.
do you need the Housing or the outlet piece. the piece that covers the thermostat (outlet) or the piece that it sits in.. (housing)

(note: that diagram is for 7mgte)
your looking at probably 30 dollars for the outlet (the piece that covers the thermostat ordered from a local dealer, according to the tsrm. (probably dated))
