Great part! Just know that this a Univar copy of the Scott version and it is well built. The bushing sit up a little higher than the surface of the metal making eyebolts a bit of a hassle to space correctly but they are steel bushing and should last a long time. Do know that you will need to match drill for your specific rudder bolts. I guess I should of know that and just made it a hassle to have to drill the component. That said, its as solid as it could be in the rudder. This actually made the steering a bit tighter. My last one must of been off a salvage plane and didnt fit great.
