Any problems with using a 100TD Instrument Cluster

[Steve]

Hi

I,ve been having problems with my Instrument cluster in a 99 Reg Bravo 75TD and was quoted £350 for a replacement Instrument cluster. (Part Number 4652-5531) Not bad as the car is only worth a max of £1200!!
I have sourced one which is for a 100TD (Part Number 4652-5536), will this cause me any problems?
i.e. Innacurate speed reading etc

cheers

Steve
