I install a 2 inch trail master level kit today and i went to get my Front-End Alignment and they said my caster was off just a little bit but i need some caster kits. i called ford and they said the bolt was $8.75 and the spacers were $3.61.How many do i need? Do i need them for the top and bottom.Can i put them in my self cause Big 10 tires want $150 to put them in plus the alignment.

 

It sounds like they were talking about "CAMBER" kits, not caster. You need 4 bolts and 4 washers. They don't install top and bottom. They only install on the upper control arms; front and rear mount. Yes, if you search and read about this topic, you'll find it can be done easily. There have been alot of tips in the "Lightning" area. This photo shows where the eccentric washer will replace the factory one-sized shim:
