Welcome Nick!
I used to jump out of a BN2 at Sibson - just to the north of you.
Anyways...... I think your best bet is Texas Air Salvage. They usually have feathers off a 150 in stock. Be a oest to ship - but I doubt you will find the parts.
Though you still might want to try and find a bellcrank. Any you get on a rudder is bound to be worn.
