1966 Dodge Dart
dragnut, sorry it took me so long to post pics. I saw this the day you posted and I totally forgot about it. I welded the radio area shut with a piece a metal before installing the gauges. If I were to do it over again I would expand the dash a little lower as the bottom of the gauges are off the dash panel slightly. There is just enough room for all the gauges to fit and it would have been easier if I would have gone with all small diameter gauges. However I bought them as a used set so that's what I ended up with. Here are some pics.
I put the radio in the glove box so its kind of hidden.
Hope this answers any questions you had. If you want to see something else let me know.
Thanks Rod
