I'm trying to pull the grill out of my Riviera, or more precisely, I'm trying to pull everything I can out of the engine compartment in preparation for the engine removal. For the life of me, I can't figure out how to remove the radiator support asm. Pulling the upper deck is fine, but the piece that remains on the top, the bar that it all bolts to, I can't figure out how to get it loose! Ideally I'd like to pull the whole support, just to get it out of the way, and pull my grill out, again, just to get it out of harms way. Any insight?
