help with Dash Differences

i have a 1970 Dodge Dart Swinger, 318. i have the longer dash and seems that there is nothing aftermarket to fit new gauges in except for the Intellitronix DIY setup.....not a huge fan of it really. while looking for a possible replacement i have come across other year dash bezel/gauge trim pieces that "look" to be the same style and/or the same size and screw hole placement. Are the 69 and 70 the same? what is the opening size for the cluster?

mine is the actual picture the other 2 are just what i can find that looks the same
