Radio & Mounting Advice

[floridaskater]

I have a '65 Suburban. The prior owner cut out the area to mount the original radio, so there is a rectangular opening currently.

I would like to put in a radio that looks era correct. However, it would be nice to have blue tooth as well.

I'm sure some of you have done the legwork on projects like this already. Hoping for some advice here on what to buy, where to buy, how to deal with the hole in the dash, and speaker placement.

Thank you.
