Front clam hinge pins?

[Davie M12]

Started resealing my floor today and the front clam hinge bolts are seized solid! I can't budge them and the R-clips are stuck in there too! Looks like the clam has never been off since the car left the factory!!
Anybody any ideas on how to get these out or any other way to get at the 6 bolts that go through the front floor into the area near the PS cooler?
I can still continue doing the main floor section but will need to tacle this at some point!

Hi Dave , I had this issue in the end plenty of heat and brute force but it was a pain !!!!!

Thanks Tux! I thought about heating them but don't want to risk melting the clam or my nice Tuxman carbon splitter!!
Just gave them a good spray with plusgas and will try again in the morning!

Got it eventually!
The pin was seized into the bush and the weld broke getting it out!!

Cheers,
Davie.
