There are at least six different types. The LE500 is very different, rare and sought after, so you are unlikely to buy one of those by mistake. Early MGF units may be identified by MG logos on the two main gauges and a mechanical odometer. These definitely will not fit. The later MGF dials have the LCD but no MG logos so you are looking for the following combination for a TF: MG logos and the LCD. You will also need to ensure that the rev counter is at the same redline as yours.
