Longer ratio gearbox for hdi

[pugbug]

And I thought this was going to be easy...! Theres a place not too far from me, who's willing to do the job. Swapping the diff looks easy, the casing visually looks identical.

it doesn't appear to be very labour intensive.

So just to confirm it's the entire second shaft and the diff that'll need swapping?

It's the only time I'll ever get a chance to do this, would be awesome cruising at motorway speeds with lower revs, over 80 and the revs are tooo high!
