old rivet-on brake disc to newer bolt on brake disc 337

[Bill Tucker]

I am a new member here, so I am probably addressing something that has been seen in the past and would appreciate any help on this. I am working on a Comanche 180 and will be replacing the old rivet-on style brake disc/drum to the newer bolt on type brake disc with applicable wheels and brake assemblies. This 180 has the dual fork main gear. I am in need of a copy of a 337 that has been previously approved and had this conversion done on it. If you have part numbers for the wheel/brake kit, that would be a bonus too. Any help is appreciated. Thanks, Bill
