Expert Reply:

The Electric Trailer Brake Kit - 10" - Left and Right Hand Assemblies - 3,500 lbs # AKEBRK-35 has a mounting pattern that is typical for 3,500 lb axles. The center on center horizontal measurement of the mounting bolts are 2-7/8 inches and diagonal center on center of 4 inches. You can see this with the mounting flange # 4-35.

I can't confirm the fit of the hubs on your trailer without knowing if the spindles on the axles are the standard length or not. The standard spindle length leading up to the stub (shaft length) is about 5 inches. This is the case for spindle # TRU84FR, which has an overall length of 11-1/4 inches and a stub length of 6-1/2 inches.
