Such win man. I love the write up, I will be doing this on my z. Now, I am only 5' 10" but I have 76 280z belts fitting in my 72. They are a PITA, do not fit right, and they don't really work with my seat. With this setup I will be able to get the belt in the seat where it will hold me in better. Make me feel a million times more safe, more easy to operate, and it looks more clean!
Thank you for a great write up!
EDIT: Clean it up a bit and I, remember opinion, I think it is worthy of a sticky.
