Hello
I pulled the trigger on new synchro for my trans, I bought them as was listed in this thread, and they are the same listed in Conceptz and z1 websites
Built Manual Transmission
parts numbers as follow
Reverse gear synchro: 32631-CD000
1st gear synchro: 32620-CD401
2nd gear synchro: 32620-CD008
3rd gear synchro: 32620-CD405
4th gear synchro: 32620-CD01B instead of CD016
5th-6th gear synchro: 32604-5X00A
Last week my mechanic has the time to work on it, and we opened the trans, but we had an issue, all of the parts fit without an issue except 5th and 6th, where they were different than the ones came originally in my trans, here is photos to show them
Up old, down new
left new, right old
So, I would like to check if anybody knows what is the correct part no. to order it, I tried to search a lot and found different part which is listed for 370z 5th 6th synchro which is 32604CD105 but the photos I saw look the same as the one I had.
