September 26, 2013
This product is well displayed for a older popular rear brake system used on many types of vehicles. I would like to see if parts are available for those of us that have this system in older form and need the non wearing parts ( namely E-brake levers ) as designated by Ford. Great item for us old schoolers
Pros:
  • only found at speedway
Cons:
  • need to sell seperate brake parts
Yes, I recommend this product.

Sorry we do not offer a drum brake kit for the big Ford old style axle flange. We have several disc brake kits such as 91031902 and 8351407139.

Part # 91031937 These drum brakes work with the New Style Big Ford car 9” rear ends with 2.5” axle offset and the 3.15 bearings. If you have the older 9” with 2 3/8” offset we offer kit number 91031939. The kit will not work on the pickup rear ends or the real early 9” from 57 thru 59.

This drum kit is designed to work with the New Style Big Ford 9” which has a bolt pattern for the backing plates of 2” vertical and 3.562 horizontal. One important thing when using on a rear end not specified is the offset of the axle which is 2.5” from face of axle to face of the housing that has the 4 bolt pattern. Center hole in backing plate is 3.150" and the attaching bolts specified are .381 or 3/8”.
