A friend of mine has a 90 Mustang LX ragtop - here's a current pic of the vehicle in question:

Last week, I located 2 hubcaps (from a 79 Fairmont) and noticed that her power windows are inoperable, as well as the RH quarter glass missing.
I have hit several FOX-3 Mustangs in the local Pick-A-Part this afternoon, pirating several parts, and her latest addition is an 84 ragtop - the floor shifter does not work (early FOXes have a floor shifter which has a steel cable lifting the detent lever - I have confirmed this when field-stripping an 82 3-door hatchback.
I am not a FOX-3 specialist, and have been servicing her vehicle ever since.
