1963 c10 swap

Hi
I am new here and own a 1963 c10. I am looking into swapping the 350 for a 6.5L diesel. Can anyone point me in any direction on where to start?

I am not a mechanic and would have to have the work done for me. I am in the NJ/NY area. Does anyone know a good mechanic that takes on projects like this?

What are some of the things I will need to keep in mind through the process? Can a diesel go into this truck to begin with or Am I wasting my time?

Any help would be appreciated.
Thanks
Bob
