well after finding out that my 3rd gear synchro has bit the dust, i have decided to rebuild my trans myself. I have enough knowledge about this kinda stuff to do it i think, if not i know some honda mechanics that would help me. Does anyone know what the 3-4 sunchros cost? has anyone done this before themselves? IS there a good manual that says how to do this? also what is your guys feeling on a phantom grip lsd? good? bad? i would even consider i type r diff if i could find one for the right price. any input would be greatly appreciated on this subject.
