WTB: V8 K member for my duster

So here are som pictures.....I found that it is an original /6 car and it is obvious now after some research, but you would think the adapter mounts they used would fit a little better.....just poor setup....definately going to put a V8 K member in it....is there anything else I will need to change it over....It looks like the steering will be fine...but this my first Mopar.
