coastie,
I did the same project, should be on an older thread. I used an oscillating saw all along the edge of the existing sole, pulled it out as one piece and refinished it. Once i had all the vermiculite chipped away and cleaned up, I used wood which I glassed in to hold the redone sole at the correct height and orientation. A few stainless buttonhead screws through the sole and into the wooden stringers keep it secure and allow me to remove it again anytime I need access in the future.
keep the pieces you've removed and use them as a template for the new one
