firstly you can use
- mk2 gti 8v box
-mk3 gti 8v box
-mk3 1.8 non gti box
-mk3 tdi box
all have rod change ,all basically the same (ratios may vary ???)
problem with mk2 boxs is the diff pins are made of cheese and sheer killing the box
normally a big hole in the bellhousing
so unless you buy one already reconned with stiffened diff pins you could put it in and blow it /or not its a risk???
your best bet is mk3 gearbox 8v gti or tdi no cheese bolts
mk2 8v gti is the small spline clutch type you will have to check if the mk3 boxes are also small spline , if they are large spline you will have to upgrade everything
idealy you want a recon box with a receipt proving diff pin upgrade , i have seen them up on ed38 for as little as £50???
But thems yur options
fitting wise its a dirt heavy pain in theass done on the floor and you will need someone who kows what their doing
but 2000 is WAY too much i say get the parts first
then find a nomad to fit them ;-)
