I'm new! Question about '93 Notch
                    Hi!  I'm a new member.  I bought a '93 Royal Blue LX 5.0 Notch a few months ago.  I have owned several Mustangs ('67 coupe, '87 GT convertible, and an '89 LX 5.0 Notch).  I have a question about one of the codes on the data plate on the door.  The TR (transmission) field indicates 2BOSS.  I know '2' indicates a 5 speed transmission, but what does 'BOSS' mean?  The car also has radio and air conditioner delete and manual windows and door locks.  Any chance of this being a rare production car?

That doesn't mean your car is not rare. I think it might very well be in a very small number of cars when considering the deleted and manual options that you mention.
TR 5 character value; First character indicates transmission type, characters 2-5 indicate spring type, Frt/Rear.
My guess is that you have an SSP mustang (Police). Check the buck tag, behing the driver's headlight.
