seat lowering brackets

[67ss&99ss]

For those of you that have installed seat lowering brackets, were you able to retain the gas tank in the factory location, or is it mandatory to relocate the tank? I don't see this information posted on Brother's site or the Full custom fab site. I assume these are currently the only mass produced options for lowering the seat? My line of sight is too high through the windshield and I will be doing a conversion from auto to manual so i want as much room and to be as comfortable as possible driving my truck. I want to be able to daily drive it or take it on trips.
