The Electric Trailer Brake Kit - 10" - Left and Right Hand Assemblies - 3,500 lbs # AKEBRK-35 will bolt onto the standard brake flange like # 4-35 that is 2-7/8 inches on center and 4 inches diagonal on center. I've attached a photo to assist.

The bolts will be 7/16"-20 and the Mounting Hardware for 10" Brake Assemblies # BRKH10B will give you the necessary lock washers and nuts compatible. The holes range from 15/32 to 1/2 inch.

Answer 6

We do, but we also have this spindle with the flange already welded on with the part #TRU74FR. Since the spindle part #TRU24FR normally fits a 2-3/8 inch diameter axle the correct flange would be the part #4-35.
