Looking for some guidance. 68 Fairlane content inside.

[Randle2I]

I have a 1968 Ford Fairlane (3 on the tree, straight 6, base model) that I'm looking to upgrade the suspension on. It's nothing fancy and it handles like an old 1968 American boat with original suspension would, but I would like to modernize it a bit. The problem is it's not a Camaro or Mustang or Chevelle so parts aren't exactly knocking on my door waiting to be installed. Without going crazy and modifying the frame what would my options be? I'm new to the whole suspension thing so any help with good products, bad products, what to look for, etc would be appreciated.

TIA
