Inspection Questions (Classic car material)

those are great links. but they are just for Pa in general i asume. so im lost as to what is more relevant the county or state? and i guess it really does not matter anyways cause any shop i go into in butler county trying to prove a point will just get me funny looks. i dunno maybe i should just accept the fact i have to run the emission crap for now, or just get my car done in allegheny county which i have no clue if i can since its in butler?
