Dusted75

So I’ve been looking to buy an old Mopar cheap and decided that I want a duster, currently I’m looking at a 75 Duster roller for $6k, and someone nearby is selling an old 440 with 727 transmission. Trying to figure out what all I would need to put the two together on a budget. I won’t be doing the work myself likely the bulk of the job will be at a shop I go to frequently or by friends trying their best. Just want recommendations on things like suspension, cooling, rear end, drive shaft, mounts/k member, things like that. Just enough at the moment to get it reliably running and maybe spin the tires here and there, I intend on driving somewhat aggressively but odds are it’ll never see a strip. I live in a small town so my options are somewhat limited on what I can find and who can do what for me but essentially please help with my junkyard dreams lol
