You need the mk4 02J shift tower. Not the early type that's similar to a mk3.
You may have to rebuild it if the bearing is loose. You can use the later type of relay lever and a TT short shift if you like. These parts come with newer style Bowden cable clips.

You can modify a mk4 shifter to fit, Or may be easier to fit a polo/Lupo/Ibiza one.
I used mk4 cables and cable bracket with an ibiza cupra shifter. You just need to drill a hole an fit a bolt to the front of the housing to fit it nicely.
The rear bolts up to existing mounts in the tunnel.

Shows mk4 and Ibiza shifter comparison. I used mk4 cables.
