Looking to take the 140 speedo gauge with attatched chip-board and putting it into my '88 bird. Question lies there, gauge and board is out of an 85, and my car is an '88. Anyone know for sure this will not work? And what makes the guage coordinated to the 140 reading? The chip board or the hardware on the back of the guage itself? And how easy is it to swap out odemeters? Don't want to deal with manually keeping track of miles and deal with odometer fraud the next time i forget to say that the mileage is off. I tried a search of "changing speedometer" and "changing odometer", both with no results to what i'm doing, not to mention most people just want to swap the entire cluster, so any help is appreciated! Thanks.

Here is a few pictures of what i'm talking about if anyone can help me out any. Thanks!

 

Jut put the speedo head (or the entire cluster) into your car. It's that simple, but you need the driver board above the gauge as well for it to work.

As for the odometer, take the needle and 2 screws out of the gauge face (mark the needle position first so you can put it back in the right place later or you'll spend either weeks or months trying to get the speedo right), take the gauge face and the plexiglass light diverter behind it off, take out the screws holding the odometer assembly in place, undo the motor from this, and take it out. Do the same to your other gauge and swap the odometers.

 

Sweet, just what i needed to know. Just hope after all that the guage works, lol. Thanks!!

 

any luck with this i wanted to put an autometer speedo in (part number ATM-3995) it is 5in mechanical. so any help would be great

 

actually as of recently, the car was taken off the road, this is one of the things i plan on doing in the near future. As far as putting in after market guages, not sure how smoothly that will work in a factory cluster. As soon as i have completed the switch, i will bring back results if it is truely a bolt in procedure.

 

it will not fit in the stock location without cutting the dash. A 3 3/8 can be made to fit in the factory pod, but its tight and a bit of work
