MK5 Golf Wing Removal

[CJM36]

Recently bought a MK5 Golf for a steal. 1 owner, full VW History etc etc.

The wings were rotting, however replacements even came with the car!!

Although I’m struggling to get them off. Every bolt has been fine except the last two below.
They are loose, spin freely, and can see the thread spins around the back. But they will not come off. At all!

Any suggestions/ideas/knowledge greatly greatly appreciated!

Ditch that foam while you're at it, that's where the rust starts
