I want to convert back to the original. Which wires need reducers? Voltage? Gas? I assume Water temp is ok to hook up as it is. | | |

Everything else should be fine, unless the copper tubing is damaged on the mechanical oil & water gauges (I'm assuming it has mechanical gauges :confused: ). | | |

Since you likely have addressed the speedo, only the other cluster is needed and that's reasonably affordable and you can turn in your core for credit. This is a bolt in option and solves all the problems in one shot. | | |

Or are looking for low buck solutions in these times. I just spent $25 for 50 gas gauge voltage reducers from www.digikey.com. These are 1.5 amp 12 to 6 voltage regulators for negative ground. (Item #NJM7806FA). It was cheaper to buy 'em for the whole fleet than to just buy the one I needed. Also, I'm sending this via FREE wireless internet from my iMac with new card installed. Such a deal!  | | |
