W126 AC Oil quantity check?

All

I am attempting to bring my AC back to life on the W126 89 300SE with a Denso 10P15C Compressor. I have it all dissassembled, flushed (except the muffler) and will be putting it back together with a new compressor, receiver/dryer, sensors on receiever/dryer and expansion valve. I am keeping the system R12 2.9 Lbs and I am using Mineral oil. I have been searching for a quantity. I found a link in the forums that inidcated 7.75 Oz total oil for the system. Is that the correct total ammount for this system?
W126 manual stated to put 120CC or roughly 4OZ in the compressor.
I will then need to distribute the rest of the oil to the Evaporator, Condensor and Receiver/Dryer.

Does the total of 7.75OZ sound correct. The info is from a Napa Cooling Belts and hoses catalog Found the link in the forum and also googled it. http://www.napabeltshose.com/downloads/download_common.cfm?file=NapaCapacityGuide2-8-05.pdf&folder=news&view=napa_hc

Thanks!
