Like the subject states I'm trying to figure out if the speedometer gauges are interchangeable. shows two separate speedos, one for 73-78 and one for 79-87. Im currently having an issue with my odometer, the speed works but the odometer is stuck at xxxx.9 and clicks when trying to turn over to the next mile. It did this after i installed a new speedo cable and packed it with graphite powder (only thing they had at all the auto part stores). I actually pulled the speedo cable off from the transmission and used a drill to reverse the odometer, it ended up clicking the same way once i got to 0 and would not go to 9, i said oh well and put it back on the trans and drove it, somehow or another the odometer started to work again for about 20 miles and started to get stuck again. so im at square one again.
