Just updating this thread....
I pulled the carpet and notice the access hole was already cut and as expected the bow was full of foam. For better or for worse I removed the foam. Took about 4 hours and I used a spade shovel, crowbar, sawzall, and a cats paw. Ended up filling 5 black trash bags of foam. It's slow going as you get started but eventually you get bigger chunks as you chip away.
