I'm new to the sight and was needing help finding out what may cause my guages to peg out to the max . I have a 1968 bronco , it has a 170 straight 6 , 3 speed manual . The guages were working fine and one day they peged out . I changed the voltage regulator , the alternator , and the oil sending unit . The guages affected are the oil , temp. , and gas . I read in some of the topic questions about a voltage regulator for the instrment panel . Could someone tell me where this is located ? I bought a 1968 wagon original uncut rust-free . I have since put on a 3 1/2 " WILDHORSE lift , dual front shock mounts , inboard rear shock mount , 2 " body lift , Tom's bronco front buckets ,fold and tumble rear seat , 6 point cage , 3 speed floor shifter , twin stick dana 20 shifter . I love my bronco but wonder sometime if I have lost my mind . I always am wanting more disc brakes , power steering , v-8 ... it goes on and on . Glad I found this site and hope to be a part of it . thanks in advance sam
