66 Burbood floor

[subloudon]

I have a 66 burb and I 'm in the process of installing a 700R4. After removing the old trans, I started to inspect the wood floor while still up on my lift. I used a screw driver and poke every area I could .There is no rot or soft wood I could find. But the wood is weathered with some cracks and worn. Does anyone have an idea on the best way to clean the wood and what could be the best thing to seal it with . I'd appreciate any help!
