Advice on how to replace damaged fixed portlight on my 2002 Catalina 310

Catalina 310 Annapolis
I have a crazed and cracked forward portside fixed portlight on my 2002 Catalina 310 that I hope to replace myself. I plan to get a new portlight acrylic lens fabricated locally here in Annapolis, MD where I keep my boat. But I need some pointers on how to remove the old lens and install the new one. Anyone done this before?

Thanks!
