Looking for front stock springs Non fatty drivers side marker light

ey guys, I just acquired a set of no brandB rear adjustable camber plates, non pillowball. Now I have no idea how to install em (noob, I know). Do I take the top hat off from the 4 allen bolts? If so, how do I then take off the top nut that would be to adjust it?

i went to this place last weekend http://i154.photobucket.com/albums/s263/aiche_photos/resortquest_zps169b5671.jpg

So everything I find searching pertains to 2.5 vs 3. My concern is 2.25 vs 2.5.   So I have a 2.5 tep downpipe and some old 2.25 strait pipe bolted on with some coat hangers (quick fix). I need a proper exaust. So exaust shops quoted me $300 and up for a finished job with parts, but I'm low on cash and all.   Is the 2.5 exaust on an all stock 88 worth it? Otherwise I can just grab a flex pipe, resonator, and muffler and just splice it all into the 2.25 pipes I got for under $100 and be done.
