I found a article regarding rear drum replacements for ford 9 inch rears. I guess back in the day people for performance used fairlane rear drums as there 3 inches wide compared to the typical 2 inch wide ones on our cats. Has anyone done this conversion? If so where did you buy your drums from? I got the rear brakes off my car and was going to go disc but seen this and decided to go this route.

As I recall the 3 inch brakes were from the Fairlane Station wagons. I’m not sure if it is a easy to find set any more. But good luck and please document it here.
Couple of things to consider.
- Backing plates are different due to the post at the “top” of the plate. It is taller for wider brake shoes.
- The wheel cyl size has been calculated for proper pressure on the shoes. If incorrect, locking up rear axle or no rear brakes…
- Considering the minor amount the rear brakes add, the $ spent for this mod or disc rears is kinda a waste of $$ IMHO
