for the position of the needles, you just have to kinda remember. i wrote down the general location, and then just messed with them for a lil bit to get them set again.for the oil pressure and the tach, you can turn the key on (don't start your truck), then just put them at the "zero" line. put the speedo right above the stopper, and the battery and gas guages will have to ba a memory thing. you don't really have to have them dead on because the dummy light will come on at the same time no matter what the needles say.
