bone collector

i have a 87 22r pickup bone stock except 31 in tires. I have done a lot of little things to the truck like de smogged it and painted it. just looking for new cheap projects to work on. i would like to work on the suspension ( ihave a set of f-150 springs laying around) or something else. Kinda looking for ideas, easy tricks that make a big difference. what should i be working on??
