another smog pump question?
i removed the bolts from the back of the heads and they dont look like they are 5/8 they are alot smaller than the ones i bought from summitt, its dark now so i cant mess around anymore tonight, but did the CA cars have a different set up or the 88s have a different set up. any ideas

RE: another smog pump question?
the thermactor holes are 5/8" thread, the bolts that hold the smog system on are much smaller... but believe me... you bought the right size pieces
see the top right hole is smaller than the one almost directly below it...
the larger hole is your thermactor hole... thats the one you plug up
