original radio for a 65 Cuda

Ok since no one else commented I will give you what I know. I don't have measurements but if you want an original radio I have one. The problem is the way it mounts I think you will have issues. The square is very small and flush with the dash the way the radio mounts is it goes in from the back comes through the dash and then the plate goes on a nut goes on to each of the dials and then the knobs. The plate is used as a weight disperser. Hope this helps and I am sorry I don't have better information.

As a side note to order a radio the beast way to determine fit is to measure from inside of one dial to outside of the other then measure the size of the hole for the dial and divide by 2 and subtract that from each of the dial to dial measurements. That will tell you the center to center of each dial. From there the plate can be any size. Also be sure to measure the center square area to tell you the size of the display.
