My 120 mph non-rallye speedo is reading incorrectly and bouncing. It will read 25 MPH while waiting at a stop sign and usually reads 30+mph too high.
I have a 73 chassis manual but not a body manual, so the only thing it mentions is aligning the adapter plate under the hold-down fork. Supposedly it has the original speedo gear in the transmission, and original rear-end gears with approximately correct size tires.
Before I go ahead and pull the gear and cable, any suggestions ??
Is there a way to calibrate the gage or sent it to a reputable rebuilder ?
According to the previous owner it worked just fine a few months prior....
Thanks.
