You are lucky to have something that was special to Gramps. I don't know how old you are but before going to radical with additional lowering think about Gramps and how he would feel about what you are doing. When you start to go to much lower you will need to do modifications that are tough to reverse and may regret later. I am sure you plan to keep this truck a long time.
Good luck with your truck do what you want but keep him in mind as you do.
