Anyone have an acceptable substitute for the taco plate oil temp sender for the '73 combo gauge?
I have a 1974 car, but according to P914.com I have a 1973 combo gauge. The car also has an appearance group center console installed, but the oil temp gauge was not connected there; the sender wire goes straight forward through the harness to the dash. I'm guessing someone added that later. My current problem is that the oil temp sender in the combo gauge just barely comes off the peg. At an indicated 220 degrees via the dipstick thermometer, the gauge is just about a needle width off the left white line, and rarely moves any farther. Given the variation in installed equipment on this car I'm guessing the incorrect sender is installed back there; since I'm about to do an oil and filter change I'd like to replace the temperature sender at the same time. Info/ideas appreciated on this mongrel. I've replaced the center console temp gauge with a VDO pressure gauge; Chris Foley has a nice steel-braided extension line that will allow me to remote-mount the VDO sender. Alternatively, I actually have a '73 non-appearance group fuel gauge. If the engine has the correct sender for the appearance group oil temperature sender (how do I know?) then I can consider re-installing the oil temp gauge in the center console in place of the clock (which I've disconnected to reduce battery drain) and wiring that up instead, then install the '73 fuel gauge. The joys of 40-yr-old cars... Greg |

Because I know that the forum has been waiting with bated breath for the results ((IMG:style_emoticons/default/dry.gif) )...I replaced the factory 200C sender in the taco plate* with a VDO 150C sender, part number 323-055. Gauge now comes off the stop and the range is very similar to the JPG attached below for the early gauge that I have. I was getting 235 on the dipstick thermometer and the gauge needle was right across the "E" in "Temp".
I'm guessing 235 is not a terrible number for fresh Brad Penn 10-40 on a 75 degree day? Got the VDO oil pressure gauge working thanks to Chris Foley for the remote mount oil line (call him for details). So the center console is now oil pressure, oil temperature, and volts. Thanks for all the feedback. GA * Why is this called a "taco plate"? Foley says it should be call a "tortilla plate"...
