Pro Grill install help needed

Like the title states, I’m trying to put in the grill now and these 3 lower nuts and bolts are giving me a lot of issues. The top 3 is fine to come out. This is my second time giving it a shot so I’m hoping someone can come up with a solution for me. I’ve tried wd-40 also. But all it does is screwing as I go and stripping some plastic along the way. It’s like it’s just freely spinning and won’t come undone. The space is too tight for me to use a needle nose plier to hold underneath. I’m at my wits end. Please help

 

Maybe wedge with a long flat tip?

 

Thanks but I’ve tried wedges of all sizes and flat heads. It keeps spinning but won’t come loose

 

Ah man, sorry to hear this. I just did mine a few days ago and had no issues. If you don't care about the old grill, might be easiest to just sacrifice that plastic. Break it away and get some pliers on the metal.
