Need some help from the number guys. I purchased an AM FM radio a few year back as a low cost alternative to the correct AM FM thumbwheel radio for my Cuda. I believe it's for a Dodge truck since it doesn't have the curved face like the C body radio's do, and is a monoral unit . I want to sell this now, but want to give an accurate description to potential buyers. Can anyone tell me what part number 3635149 (Motorola Mark IV) fits? Any help is appreciated!
