66 Buckets into 67 Barracuda

I am going to attempt to install 66 buckets in my 67 Barracuda. But I need to remove the floor pan bolts from the seat tracks so I can better check how they sit on the floor pan.

After removing some of the rust, it looks like they are the square carriage type bolts and should be removable. I tried to pound out one with a piece of wood, but all that did was put a hole in the wood.

Before I get too rough with these, I need to know, are they removable?

How much different are these from the 67 seat tracks?

Are 67-69 tracks different than the 70 up tracks?

Does anybody want to trade these for later seats or tracks? :toothy10:
