I have the following radio and cassette player/recorder acquired years ago. After see your post, decided to dig it out.

Originally I was told it's for a C-body. However, I just entered the p/n (3501080) found on the cassette base cover and it appears to be for an A-body. I can't locate a p/n on the radio but it's cabled correctly for the player/recorder so it appears to be the one that goes with it.

Perhaps one of you who's more up on these radio-cassette P/R can help me out with exactly what this unit is.
