Hey guys.

Installed a heater core, which involved taking off the front panel and glove box. Starting to put it back together now and I can't figure out what this goes to. Anyone have any ideas?

that goes behind your radio. the black rubber piece that sticks out the back of the factory radio fits into it to keep the radio stable. if you have an aftermarket radio, you dont need it.
