Owner Notification Program B93 Floor Pan Reinforcement
Check
the Ford website &/or
the NHTSA to see if your VIN is affected.
Affected Vehicles:
1989/90 Bronco and F-Series SuperCab with Captain Chair Option
Ford Motor Company is providing a no-charge Service Program, Number (B93), to owners of certain 1989-1990 Bronco and F-Series Super Cab trucks equipped with captain chair option.
Reason For This Program
The seat tracks on your truck are attached to non-reinforced sections of the floorpan. This may cause the floor pan to crack at the seat track attachment. At no cost to you, your dealer will install floor pan reinforcements on your truck.
How Long Will It Take?
The time needed for this service is about 3 hours. However, due to service scheduling times, your dealer may need your truck for one full working day.
Call Your Dealer
Ask for a service date and if parts are in stock. If your dealer does not have the parts in stock, they can be ordered before scheduling your service date. Parts would be expected to arrive within a week. When you bring your truck in, give the dealer this letter. If you misplace this letter, your dealer will still do the work, free of charge.
Refunds
If you paid to have this service done before the date of this letter, Ford is offering a full refund. For the refund, please show your paid work-order to your Ford dealer.
