 If you can get the wheel well out ? Or to get the back to drop down, That will be a big help for the bottom bolts. The rest will not be all that bad.

Cut out the vent and repair with heating duct.  Takes about 20min to change that way

I'm not sure if AC stuff will be in the way.............but you can get to the heater core from behind the glove box.

You have to remove the glovebox door though.

I DID ONE IN A 96 CADILLAC A COUPLE YEARS AGO. TOOK OUT THE GLOVE BOX, REMOVED A PLASTIC COVER AND THERE IS WAS, PRETTY EASY FOR BEING IN A CADDY. THAT BEING SAID, SHOULD BE REAL SIMPLE BEING A 79 CHEVY.
