Slight Modification
Had to tack weld it to the axle because the keyway didn't extend to where I needed to mount the brake drum. But otherwise it bolted up perfectly and does it's job.

Don't buy unless you want to Waller out the mount holes to fit anything.
Holes don't line up with any other Brake drums or sprockets.

Confirm that the bolt circle on your rotor will fit this before buying
Looks solid but the bolt circle does not fit the Probat hydraulic brake kit rotor
