i read somewhere that you are not supposed to move the engine or opti-spark while the dist is off the engine. seems to me it wouldnt matter because the shaft between the two is splined so that it wont go together out-of-sync. just wondering because ive moved em both. if the shaft will only go in one way then you cant put it together wrong, correct?
fyi: i also read somewhere that vatozone now has complete remanned opti's for $130 or so with a lifetime guarantee. just in case. i bet a guy could take his non-vented in there and swap it for a vented one and they'd never know the difference.
