Well that is why I asked about DIY skills. My 75 is going to have a coast to coast OF. It is only going to cost my 15 bucks for the glass and that is in black, well very dark tint. The color is in the glass not a film. A 10 dollar hole saw. And the plumbing.
Oh yea you will need a blank tank.
What is the cost difference on tanks, from one with the OF or one without the OF? Also the ones with the OF, do they come with the drains? When I was looking at them I had to purchase them separately.
