83 power ram 50

ok i have a 83 dodge power ram 50 with the 2.3 liter turbo diesel. however the engine dont work :shakehead. so my question is does anyone know where i can get parts for that engine or if that would be to much of a hassle then what all engines will bolt up to the transmission (it's the straight shift)? any help would be appreciatted.

well i'm thinking that repairing the engine that's in it is probably not going to happen so does anyone know if a 360 will bolt up to the transmission?
