The RPM gauge doesnt work at all and the oil pressure gauge moves around when it wants too.. Whats up? Everything else works fine

did you check the connections at the coil and pressure sender? the oil pressure guage is probably just the sender, as for the tach it could be a multitude of things

Check your wire that goes to the distributer to see if it fixes your tach. also check the sending unit for your oil pressure gauge. Mine was bouncing all over the place at one time. I finally replace the gauge AND the sending unit. Works like a champ now. Oil pressure sending unit is around 10-15 dollars. The gauges do go bad after a while. or they may never go bad. I have a 85mph cluster as well as a 110mph cluster ill sell you for 30 bucks plus shipping.

i have the same problem. my tach just pegs 7k. ive changed entire clusters. still nothing. from what i understand these tachs get inaccurate all the time. i suggest trying another tach and going from there.
