Quick question. In the middle of a rebuild and I have two 2nd gears. They are both double synchro but one has engagement teeth that are at a 45ish degree angle and the other is bi-directional. Is there an advantage to either one? On the input the 3rd gear is bi-directional and the 4th gear is 45 degree. I have a 92 input and both 3rd and 4th are bi-directional.
