What dash do you have now? And what gets stuck?
Thanks to evooox for this knowledge:
There is 2 different tacho for different engines, if you have a engine with the distributor type setup (typically 1.5 single cam) a gti or m21 dash will not work the tacho.
If you have the twin cam or the non distributor style of ignition then a m21 or gti dash will be fine.
There are no differences in wiring.
I have either the black faced m21 cluster with about 90k on clock, or the jumbuck carbon fibre faced cluster (suits the other engine) with about 90k as well.
If you have a broken gti cluster, I would like it in exchange for a good price on my cluster
Call it $50 posted for either. I pretty sure the m21 was $50 plus post when I got it. I have been using it until recently.
Cheers
