How far should i go with swapping stuff out in the front end?

I have a 64 dart and at the very least I need to go to the big bolt pattern to match my rear end. I'm really wanting to run a 14 in or 13 in wheel so I don't think disks will fit and really don't care about trying to get disk brakes. Just trying to find the most practical way to get the front end rebuilt. If it is simpler to keep the front end stock I can just hunt down different wheels.
