Also make sure to prep the area where the new bulkhead will go. I noticed old carpet and adhesive in your pictures about. You will want to remove the carpet and a adhesive and sand with 36 or 40 grit in the area that will get the new glass.
Also, I think I had about 1/4 to 3/8 tolerance between the new bulkhead and hull. I was told not have any wood touching the hull.
Finally, I am a weekend warrior, this was my first project boat. I have only have experience with resin and fiberglass before this. There are probably people with way more knowledge than me.
