Based on the shale of the cluster, it’s possible it could be refitted into the Dart’s bezel. You might contact their Custom section as I suspect they could do the retro fit.
I was going to use a 66 Barracuda cluster in my 65 Dart wagon as it had an oik pressure gauge. I contacted their custom section who said they could convert my cluster to their digital gauges, the only option at that time.
