Hey guys sorry for the newbie question but i cant seem to find out exactly which resistors i need for my tach to work...neaning that every time i go to a Radioshack (3 different ones now) and tell them the type of resistors i need they give me the deer in headlights look...i've searched and i cant seem to find any more info on them so i can finally but them and continue on to the my next project...if anyone has any part numbers for Radioshack or can help me in any sort of way i would appreciate it....

Thanks!
