What Seats Work In The Fox Body?

Any fox body cars seats will swap in that includes Lincolns too. Most passenger cars thru 04.
As far as the seat belt holder meh..... I run seats without that thing, only problem I have ever had was when my girl was driving my car she got pulled over. The cop asked have you been wearing the seat belt this whole time? Lol it was a good laugh for all three of us. I suppose as long as the cop isn't having a really bad day you should be fine.

Pretty much any seat will fit if you can fab/weld up some angle iron to the stock sliders. As far as direct fit. 79-93 bolt right in. 94-04 mustangs will fit but you sit about an inch higher, All that is needed is to combine the 2 power wires on the 3 wire connector for the driver power seat so if works with the 2 wire connector in your fox. I've had them in a few foxes and they are a nice upgrade. 05-09 fit but you need to change the slideers. Escort seats swap in. Back seats are a whole different story.
