Outer Limits 4x4 Board

Can anyone please tell me definitely if the dash instrumentation is interchangeable between the earlier model petrol and diesel GQ STs' (the ones with speed & revs main gauges and alt/oil/fuel/temp secondary gauges)

I need to get one for my 4.2 diesel as the odometer has failed and now the speedo also and it increases my options if I am able to source one from either vehicle type.

All information relating to this enquiry is appreciated, cheers

you should be able to pull the speedo part out of the new cluster and put in yours. i would imagine the tachos would be different cause the petrols take the signal from the coil where the diesls usually take it from the alternator.
