65 Valiant 170 changing RH mount and oil pump

Is it going to be impossible to change the RH engine mount and oil pump on my 65 Valiant 170? The LH mount was easy when I was changing the intake manifold gasket. I didn't even have to use an engine hoist to raise the engine up. I've got the 65 chassis manual and it says you have to raise the engine and put a 2x4 under the front corner of the oil pan to change the oil pump. It doesn't really have instructions for changing the mounts. Is it really that hard to change?
