Anyone have a 3.42 final drive?

Does anyone have or know where i can get a 3.42 final drive (or lower) for an 020 gearbox in my mk1?
Been trying everywhere with no joy- currently have a 3.64 but new beefed up engine wants better top end.
Thanks

Bumpio! come on someone must know!

I have a 4+E gearbox with a really worn syncro on 2nd if you're interested?
