I know this subject has been beat into the ground, have to find out 100% for sure about this though. I have a B16 S1 transmission and I've ordered S1 synchros but come to find out the synchro hubs/sleeves are pretty much shot. Do I need to get B16 S1 hubs and sleeves or will any 90-91 Integra work also. Gearspeed will only sell me complete hub set with new synchros for 400.00 I need 3-5th but http://www.acuraautomotiveparts.org I can get them for a little more then 300.00 and just have spare OEM synchros lying around. So if your 100% positive on the answer let me know. I don't really care either way just need to know 100% answers only

 

Well to answer the question per gearspeed they are the same parts
