I don't think the cases will interchange between the TOD and theT-176 because there is an extra lever in the side of the TOD the reverses the action of the shifter fork. This is because 3rd gear is right and up and 4th is right and down while 3rd gear is straight through. Puting this extra lever in reverses the shifter action so when the shift lever is pulled down the fork goes back. The T-176 will not have provision for this in the case.
