Alright first off. This is the only marking on the case. Not sure whether it is a cable Y1, S1 or YS1. All I know is it came off of a B16 with no LSD.

The problem is I have a nice little grind between 2-3. I just need help figuring out what parts to order. Here goes. This one is from the shaft that the clutch goes on(countershaft??), first set down from the top. Looks to me like the synchros are a little fucked....which set are these??

This is the next set down...same thing.

Ok these are from the set holding all the gears(mainshaft??)...

And finally this...which looks to me like reverse???

As you can see things are a little tore up. I am currently doing my build up and this will be finished with a Quaife. If you guys could give me a hand with the parts that are needed it would be a great help. TIA
