I agree with Jeff and Martin, problem is that with a '78 you will have to do the emissions dance every year, and I wonder how long the aircare droids will only know to look for the air pump. I bet they'll start being more strict about emissions equipment as time goes along.
Just like my dad's 80 - it passed emissions for years with only 1 cat until they started figuring out that 80s needed 2 cats. It failed visual last year due to only that.
