70 Dart Swinger guage cluster removal???

Trying to remove the guage cluster from my 70 dart swinger. It is the non rallye type, 0-120 mph, etc. Have all the screws on the front removed and can get it almost all the way out by tilting the top forward but the bottom of the cluster in the back will not clear the metal dash frame on the bottom as it has a round lip sticking down. I am afraid to do too much prying on 40 year old plastic so I am on here hoping somebody will know what to do.
