Two part reply.
Yes, your original bolts and plates will go back in just fine (crowbar is your friend). Make sure the locator plates fit between the detents so it is all flat when tightened up.
But, when you go get the alignment, the tech. will probably need the caster/camber bolt kit. I simply bought the kit for both sides and let him use them or not, as needed. NAPA flat out said I can return them if not used. My truck is being aligned as I type.
All that said, Mine DEFINITELY had camber issues when I drove it over there this morning. You could see that the angles weren't correct, mine looked like / /, not / \ or \ / which really struck me as funny. I can't wait to drive it again. (Replaced LBJs, UCAs, Rack, OTRs, and shocks).
