In Search Of a 67-69 Cuda Temp Guage

Howdy all, cosgig here! I'm in need of some help here from the family, I'm in need of a 67-69 Cuda temperature guage for Nellas cluster! Got the entire cluster all bench tested, and everything's working but the temp guage! It's been tested and it's junk! So, does anyone have a temp guage to sell that has been tested and works, and can send it out right away?? I have paypal to pay, or can send a money order! PM if you have one and let's make a deal!! Thanks all for any responses!! Geof
