Audio Systems: Delco Radio output IC, delco radio, chevy s10

Question
I have a 1991  Chevy S10 Delco AM/FM Cassette car radio that has a blown output. One channel still works and would like to order an IC prior to removing the bad IC from the PCB. Unfortunately the part number of the IC is on the Side of the power output IC that faces the PCB. Any help on a part number would be appreciated.

Answer
the last time i fix that radio was 10 years ago back them it was hard to get the ic and it was not in production aymore
i don't remember the first 2 letter it was 165 and 185
this is a mosfet ic output ,if you find it be very carefull when installing  to much head will damage the ic and electricity in your hands will also damage it
mount it in the heat dissipation block and solder 3 pins at the time
