VEVOR Electric Trailer Brake Kit, 12.25 x 3.375 Inch, 2 Pairs Self-Adjusting Electric Brakes Kit for 10000 lbs Trailer Axle, Backing Plates for Braking System Part Replacement, Fit for Trailers, RVs
The description says the backing plate has a 7 bolt pattern, but the majority of the photos show the standard 4 bolt pattern for 8000 lb. axles. Which is it? Thank you
