Pretty sure you need the black cyclinder cog thing and black drive gear.

 

Strangely I've just got back from taking the engine out of my car and splitting the box, also to change the speedo cog's for red and white ones, short story I have the above cog's doing nothing, yours for postage

you should have a red pinion and a white cog on the diff, also you need to be using a gti speedo head.

 

2649 11 red 17t pinion, 2643 04 19t white cog.

 

 

 

2649 11 CONTROL PINION 6.34 GBP

 

2643 04 TACHOMETR SCREW 4.73 GBP
