what you need is the entire shift tower from a later 02J gearbox matey. Not just the weight on top, but there is alittle housing around that that unbolts, and the entire shift tower lifts out of the box. I believe it also has a corresponding end cap too on the bottom of the box (the VW logo part)
Once you've got the shift tower, you'll need a shift unit and cables (with gearbox bracket) from a later car, then it's just a case of fitting it all. To fit it you need to drain the box oil and replace the tower, then refill the box and fit the new cables / shifter and off you go

You can then fit a TT shift weight for £20 from audi if you want to shorten it up a tad too
