How do you remove a radio from 91 Riviera?

you have to take off the front cover of dash witch means u will have to take off the cover under the lil over hang part and the screws from the SIDS of the dash and u will have to pull the climate control out witch is just a few screws near the rear of the c.c. and then there are i think 4 or 5 screws that hold the radio bracket in then one net on the rear of that bracket that holds the radio i give it a 3-10 on a difficulty scale but that is me i did mine in about 2.5 hours but i had to mod some parts cuz i bought the wrong ones
