I'm interested in upgrading the factory am/fm/cassette player in my 99 F150 Supercab. I have noticed on the auction sites two basic designs of units. One with a top that slopes/necks down towards the rear of the unit, and one with a flat top which makes the unit a complete rectangle. Are both units interchangeable in my truck? Or do i have to stick with the sloped one since that's what my truck came with? If anyone is interested in selling one that fits, let me know. Thanks

 

have a oem stock am/fm/in dash cd in my 2001 f150 scab that i would sell if the price were right. if you want pictures, let me know. email me at quickdrawf150@hotmail.com
