I have restored 100's of these radio, I think it's like everthing else ,if your looking for it you cann't find it ,if your not looking for them they are every where! Ford,Dodge,Wllys,and International radios I've seen very few of, Dodges the least of all ,althought the 48-50 Dodge uses the Mopar 802, witch is used in the passenger 46-48 and common radio built by Philco, Willys started using Zenith, then Motorola , and then Delco, a radio almost the same as the 54-59 GMC!
