You can use the 40 Ford brakes or the F100's, Obviously the 40's go straight onto 37-41 spindles but the F100's need different bearings, I worked out the bearings & seals myself and then found out Speedway sell the bearing kit.
Its pretty straightforward apart from a little material that needs to be ground off the spindle.
