29 Essex Clutch Oil

Unknown

I have done due diligence in my searches and have found that I should use 6 oz. of Dextron ATF for my clutch oil.  I can not find where to add the fluid in my '29.   I am not familiar with a wet clutch, so please give me the correct details to do this.  I have the entire assembly apart and will be installing my newly re-corked clutch soon!

Thanks,

Ken
