I need a new 2nd gear synchro in my 1950 3 speed. I have a local guy who said he had a 1953 3 speed. I went to check it out and it is an open driveshaft Transmision. Would the synchros from the open drive shaft tranny fit my tranny? How late was the torque tube used too? Also who sells synchros for the 3 speed and around what do they cost.?
