Robert , If you have not saved all the original emission equipment exhaust manifolds etc ,I would put it all in a box no matter how small it is. The current emission law says that only models previous to the 76 model year are inspected (who writes sh&t like this? Friggin politicians! ) Why not just say 75 and down require no testing. With Ca looking for a nickel under any rock ,they could change the law back to the way it was before and go back as far as 1953 with all the so called emission cures to add to the the old engines. A lot of peoples interpretation of the law is that no testing means you can do what you want when in truth all legal add on or changes will have a EO (Exctive Order # issued to it from Carb(California Air Resource Board) In the real world there are no cops looking under hoods of old cars only the ones that go in for biannual testing.But when the politicians see dollar signs let the public beware.
Dan - One never knows what C.A.R.B. will impose on us next, so I have retained all the smog related items. The car hobby in CA was not successful in defeating the latest air quality item we voted on, and that will no doubt give those who serve us in Sacramento the green light to make it much more difficult to own a collector car.
