The extra baffles are only required with the Beech controllable prop.

A couple of engine baffles also need to be added.

The wide trim tab is not required. A trim tab is required but either the 3/4 inch o1-3/8 is acceptable.

I understand that to convert my C75-12F to a C85 hp the main thing that needs to be done (besides having the correct prop) is the following:

The carb need to be changed to a 1 3/8 venturi and the metering jet to a #45 size jet.
22031-4 TRIM TAB PLATE - 1 3/8" WIDE (Required for C-85 Engine)

Have any of you had that done? If so, how do you like it? What are things to consider? Etc.

Thanks--George
