R32 Gtr Clusters

[EdGTR]

Hi all, You hear that there are two different clusters in r32 gtr,s. I was wondering when they changed and more importantly if there are any obvious differences? ie connections or somthing on the back. Also if i fit the wrong type what can i expect to happen?

Thanks

change is from 08/91 onwards, early model film on back is white/grey and late model is blue/green

u can change between the two with minor differences, speedo sensor part can be swapped between models and the face of the cluster is slightly different
