Hi I've been lurking for a while but this is my first post so hello everybody.

Long story short. Gearbox was grinding when changing into 3rd gear and then eventually jammed in 1st gear. Have removed gear box and found 3rd gear synchro missing.

Began stripping but I could do with some information before I break something. Can anybody help me please?

Almost forgot. 1997, 1.9 TDi A4, Engine AHU, Gearbox DHL

Thanks in advance
