Flap Actuator Snap Ring Configuration

My copy of the shop manual for my Debonair is a bit shortcoming. Most of the meet of things must be supplemented with a shop manual for the Bonanza 35 which I also have a copy of. The 35 manual shows a cutover serial number range for the duel snap rings installed in the flap actuators however, only the 35 serial numbers are listed an the Deb shop manual does not mention how to disassemble the flap actuator at all. Looking for a S/N reference to whether my actuators have single or duel snap rings? Also 35 shop manual shows a reference to using Aeroshell 7 grease for the flap drive cables but also list a cutover for the 35 around a S/N range in the 800's. Is Aeroshell 7 the approved grease for the flap drive cables?

Thanks

I have attached a copy of the later model actuator removal, repair, and assembly procedure.
The P/N's have changed in some cases, the repair is still the same. The actuator calls for oil meeting Mil Spec
MIL-PRF-2105 Grade 75W

Ignore any reference to the first 830-ish serial numbers in the 35 manual, completely different flap drive mechanism. The dual snap ring was discarded long before the 33's were certified, all only have one. Aeroshell 7 is the cable grease, but note only the black-plastic covered cables can have the center core removed for cleaning & lubrication; the earlier cables (exterior is wrapped metal) need to be drip-lubricated from the top. Also suggest packing the actuator bearings with Aeroshell 7 before assembly, and still use the gear oil call-out also. Last, the installation procedure is little out of order as the cable needs to be properly shimmed and installed to the housing prior to installation in the wing.
