87 Mazda B2000 ... Budget build

pretty much sums it up since i got the truck back for free i got a few grand i can put into building it



not going to crazy but going to bag it some time this year and go bed less trying to keep this truck just for the summertime since i live in Boston and my goal is not practical

can any one tell me what is connected to the filter? and what are some simple mods i can do to it to make it a lil more dependable



also im having an impossible time finding any kinds of air ride parts ...sheet metal for the bed to make some wheel wells

Can anyone point me in the right detection as to where to get an air bag kit and anything I might need to bag it

This will be my first time doing this kind of thing so any advice or tips will be greatly appreciated
