Rebuilt steering gear box with 16:1 ratio (or 4 rotations of the steering wheel) and 1-1/8 inch sector shaft. This is the standard power steeroing gear box for all 1968-70 Mercury Cougars and Ford Mustangs. Additionally this 1-1/8" box was found starting on mid year 1967 cars. The only difference between SMB-F or SMB-K is the tag and inclusion of the power or manual steering Pitman arms.
Our rebuilt steering gear boxes for the 67, 68, 69, and 70 Mercury Cougar / Ford Mustang / Shelby. We consider them to be the very best on the market. Most auto parts are being rebuilt in Mexico these days at such a low cost they can afford to pay out on warranty claims multiple times and still show a profit. You will not be calling us with any problems on this box...
Our Premium boxes are rebuilt here in the USA at a one man shop. Includes pitman nut and lock washer.
If you are trying to identify the proper steering box, the box will have a raised casting number of C7ZR-3550-A. The early (prior to approximately 5-1-1967, 01E date on the data plate) steering boxes (both manual steering and power steering) will all have used a 1 inch sector shaft, this in turn corresponds to a Pitman arm with the 1 inch hole. Later boxes all had a 1-1/8" sector shaft and corresponding pitman arms for manual and power steering.
*Notice* Most 1967 Ford Mustangs used a long shaft steering box. Typically, only S codes and tilt steering column 1967 Ford Mustangs received the SMB-K or SMB-C short shaft steering boxes.
The 16:1 ratio SMB-F box was used for production purposes on those Cougars or Mustangs with the Competition Handling Packages. The SMB-K box (same 16:1 ratio - Power Steering) is identical without a pitman arm. We at WCCC believe that the pit-man arms were pre-installed on the steering boxes for use on the assembly line. That is why they have the SMB-F tag number. For those with manual steering and contemplating going to the faster steering box, 5 turns lock to lock to quicker 4 turns lock to lock. Understand that there will be more effort involved in turning the steering wheel.
We require a good, rebuildable core with 1-1/8 inch sector shaft to receive the refundable $225 core charge. 1 inch sector shaft cores are not acceptable. Please remove your pit-man arm before sending your box to us. When returning a core please include a copy of your invoice. Keep in mind if you are returning your core to us after 30 days has passed you will get your refund in the form of an in-store credit.
