Converting to the Shelby 2 1/2" drums on early mustangs

[gt350hr]

  If the hole is too small it can be opened. Too big is a no no.

Thought I'd throw this out there for those who may want to follow the spirit of the Shelby modification but but not necessarily the letter of the law. I got this off a mustang forum that was trying to solve the same problems we are. If 11x2.25 is close enough to 10x2.5 then a complete kit including loaded backing plates and parking brake components with your choice of "racing" or "street performance" shoes is available for less than $500 at https://opentrackerracing.com/shop/11-x-2-25-drum-brake-for-small-bearing-ford-rear/ . I gotta say that looks pretty attractive for a tribute car.

Those are 1979 to 1990 LTD Crown Victoria rear brakes from a station wagon, or a police car. I have them on my Fairlane station wagon and I took them off a 1984 Ford full size station wagon. You can probably get them at a junkyard for a lot less money.

The Ranger drum mentioned above has a centering bore of 2.808 inches. 3/8" inches larger that a vintage drum. perhaps a sleeve could be swaged on the axle hub to accommodate for the difference.

Google hub centric rings. They make them in lots of different sizes and if you can't find one the right size there are places that make custom ones. You can get them in plastic or metal.
