Evaluated modifications to AeroConversions hydraulic brake cylinders and Tracy O'Brien axles. Since Tracey O'Brien has a NO RETURN policy, it looks like modifications to the anti-torque/wheel pants plate, hydraulic pistion assembly, and axle assemblies are required for a proper stackup.
Opened the anti-torque plate through hole to 7/8" for clean fit to axle. Will need to drill the through holes for the hydraulic piston body to 7/8". It appears that, with those modifications there will be additional axle mounting material that will need to be trimmed from the TBO axle mount.
