Message	Can anyone confirm what the thread size and pitch are for the following large fittings on the upper plenum: - PCV valve ports - the two large hex shaped fittings (driver's side) - large bolt passenger rear top corner My plenum was chromed a while back and I need to clean up the the threads before engine goes in car (hopefully tomorrow). I think I've got a good handle on the remainder of the smaller bore threads, but those larger ones are trickier to identify. Thanks! Inzane
