/6 Swap

Just reuse the mounts from the old Slant and put them on the new one. They'll bolt right up.
One thing I learned from doing this on my Duster years back was to set up the hoist so that the engine pivots on the driver's side mount before you pull it up, get the engine straight up and down then remove it. It comes out much easier than if you were to try and pull it on the slant. If you have an engine load leveler that would help imensly, and also have someone helping you
