Ok so I have looked all over the internet and this site and cant get a clear answer. I have a 1984 c10 with the straight 6 (250 4.1L). I want to install a oil and temp gauge because mine work intermittently (I have the light, no numeric gauge's). where is the oil sending unit and the temp sending unit located?All the places I have looked show a v8 of Some sort, ALSO I want to keep the auto choke/oil light.. will installing another oil gauge interfere with that ?
