I have a 64 TR4 w/ OD that I am restoring. I sent the speedo out to be re-conditioned and have the odometer repaired. It reads 10 fast @ 30 mph, and 20 fast @ 60. It has an 1184 speedometer in it. Are they matched to a specific rear gear? I am assuming something has been changed at some point (rear, gauge). Is there any way to "cheat" the calibration? Sorry for the newbie question, my wheelhouse is GM where you can just change the drive and driven gear inside the trans and be on your way. Thank you!
