2002 (bugeye) 4th gear synchro
 

Hi, it's been a while, in fact a long while since I been on this forum as not had a scooby for 6 years!

I've just bought a 2002 UK Wagon and 4th gear is crunching when giving it some beans from 3rd. Fine if I double clutch so I'm assuming synchro gone/going.

So looks like a replacement box - but I see different units for sale and not sure which one I need!

Is it just the box I buy or the full unit with diff?

Any guidance would be appreciated, so thanks in advance

Edit 31.8.16 - so nobody has had any issues with their gearbox - wow, well done :-)
