Front Wishbone nuts just spinning

Hello,

I am in the middle of replacing the front suspension on my Fabia mk2 Greenline.

I have got most of the bits off that I need to, just got to the front left wishbone bolts. They were really tight to get off. 2 of them have sheared completely & the third one just spins. I can feel the bolt is not spinning, but the nut turns & never moves.

I have given them a good clean, incase there was some rust stopping it.
I then tried to the drivers side & all 3 of these just spin too, not really tight.

I am guessing that I am going to need to cut them off, or is there some trick to this?

Any help would be gratefully accepted.

Thanks, Matt
