37 ford axle, juice brake question

Hello to all, and man thought i was on a roll tonight when i ran into this problem. Puttin juice brakes on to a 37 axle, the wheel cylinder hits the top of the spindle. Was just gonna grind off the top of the spindle or bottom of the wheel cylinder. But then i thought, there is probably a better way to do this with the H.A.M.B. Any help would be appreciated. thanks fellas.

 

that looks like f-100 backing plates.....if they are , you have to grind to spindles for clearance.

this is covered in the tech o' matic

 

Looks like F100 to me too.
At least these are not 39-48 brakes.
