That may be the route I go. I need to measure the backing plate and check the size. I would guess 10 inch. I wired it the same way it was previously. (the right side wiring goes through the axle and connects to the left. After they all connect 2 wires exit the loom one ground one brake?) I assume the 2 wires aren't both brake signal wires from what I see but I can take some close ups and maybe somebody with more knowledge then myself can look. The OP said he never used the brakes so I would assume they are rusty or seized. I need to pull the drum and inspect.
