b16b tranny problems

ok im helping a friend work on his ctr motor and we pulled the tranny and found out that the 1, and 2 sliders are bad. i was wondering if there is a good place to get parts for a ctr tranny i was thinking since its all apart to put better syncros in it.
any help would be great.
thank you

The transmission on the B16B is no different from the one from the 96 spec B18C-R. These transmissions are near identical to all 92+ B16A transmissions, so parts are easy to get straight from HONDA.
