The 1-200 comes from the labour involved in redoing all the lines surrounding the valve. There are no trucks of this generation in junkyards around here. I called 6 junkyards and there's only one truck with different brakes than mine with huge rust. I prefer new parts anyway, well that's not true, I prefer not having to fix **** but, oh well. The price seems reasonable to me, all labour for taking rusty, ****ty things apart. Nothing has been easy on this truck.
