Points to electronic ignition for a 318

i have a 1970 belvedere with the stock 318 in it, previous owner added a bigger cam and iv added a new elderbrock 4 bbl intake and carb..the one thing iv been wanting to change is the original points system to a electronic system..iv never done a swap like this before and was looking for some info and advice on the best way to do it..what all do i need to swap out, and what would be the best setup to put on it, or what would be a good vehicle to take all the parts from..any help is appreciated, thanks for reading
