If you have the convenience group you need the seats with seat back releases. You cannot add without a lot of pain. Will have handle in the center and the solenoid in the back. There are spacers under the seat on top of the adjuster that allow the wire to pass through for the solenoid so they are very different.
The seat adjuster are also different for vert and Mach 1 so look at them also. Here is a picture of one of mine. If the adjusters are all rusty it is not an easy task to take apart to sand blast. They put the ball bearings in the tracks then they put in a press and formed dimples to prevent the seat from coming off the track.
The passenger seat has the pressure sensor in it the drivers does not.
For the side panels make sure they have not turned to chalk. No speaker holes. The convenience group had ash tray in back R.H. side.
If you have not been to the swap meet wear your walking shoes, lol. Need sun screen and I have seen it frost. I take note book and when I buy something just leave it there and then come back and pick it up. The Hornets Nest tent also has golf carts and they will haul your stuff to your car which can be a mile away easy. There is a cost use to be $10.00
After a certain time in the day you can borrow a gate pass from vendor and drive in and pick up your stuff. I myself prefer to park in the back of the track it is closer than across the street.
I will not be there working on the Mach 1.
Also lots of Mustang vendors at the MOM the following week.
