I'm hoping that someone here has already done this and can save me a lot of time. I've got a '77 K5 with a 454. I'm converting it to a short water pump for more flow than the long style pump. I've made the new brackets and stuff but need a new lower rad hose. The factory hose hits the frame rail and a hose for an earlier truck with a short pump will not work. Does anyone have an idea of what hose to use? Thanks.
