On my 65 Valiant I need to change the passenger side motor mount. It's been sitting up for years so I was going to replace everything on that side of the motor as well. So I'm getting a new coil, fuel pump, distributor, and oil pump. I replaced the driver's side motor mount when I did the manifold and it wasn't bad. But this side looks hard. It's hard enough finding the mount. What do I need to replace the oil pump and motor mount? I know they will be the hardest to replace. It says to jack it up and pry the motor sideways and stick a block in the corner of the frame between the motor and it will give you just enough clearance to change the oil pump. Is it really difficult to change?
