Thanks guys, I'm setting up to do the repair and had a couple more questions:

A) Are there any more detailed instructions / pictures of how to get the styrofoam blocks out and to dry out the car?
B) Does anyone know the part number for the O rings on the back panel? I was hoping to replace them and do a touch up sealing job, to sort of double the effort.

Thanks for the help guys, hopefully it'll turn out fine and I'll let you know how it goes.
