69 Camaro Body bolt?

[Dream68]

I started to take out the subframe on my camaro and while turning the front subframe bolts and them not coming out I saw that the large square nut on the top size is spining inside the holder designed to hold it in place. I sprayed w/ pen. oil and let sit for a few days and still nothing. HOW DO I GET THESE OUT? Thanks.

You can try sticking a big pry bar in and wedgeing the nut. A impact make help here also as it will "Shock it" loose.

We have welded the nut to the cage before

I have had some success knocking the cages off and getting an open end wrench on them. Not sure of the size but I was able to get one at an auto supply shop. Keep soaking it with liquid wrench.

I'm with Frank...I just did this as my nut was cross threaded when I bought the car. Drill out the spot welds on the cage, tack the bolt and impact wrenched it out. Went pretty slick
