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?
