Make sure to have a good look at the top corners of your bulkhead while youre there.......the seals like to hold water there and while youve got the seal out it will be a good indication on any future work coming up!
The bulkhead that was on my 90 was trashed because of this, and the fact I bent it when I rolled, The replacement I bought is bad too, spent a few hours on it already replacing the corners!
