You had an excellent approach in post #31. You just left out a few forces and slipped up on the distances. Now you have a good sum for the moment due to all the applied forces but the equilibrant. You want to apply the equilibrant at a location such that its y-component balances the previous sum (makes the net moment zero). Or just start again and write the full moment sum out including the equilibrant's contribution.
When forces are at various angles you almost never want to use the magnitude of the force for anything but computing the component of the force that's of interest.
