Re: Europa-List: Exhaust port bolts for 914Dave,

Might be close but not quite right.

an AN5 bolt has a diameter of 5/16th inch =  7.93mm and 24 tracks per 
inch = 1.058mm pitch. The smaller diameter and the little difference 
in pitch will allow an AN5 bolt to go into an M8 with the fine threaded 
pitch of 1mm without problems for a small number of turns before it gets 
to snug.

However, the manual calls for M8 * 6mm with fine threaded pitch of 1 mm

  Michael, 

  Just a question.  Are you sure that the thread of the EGT ports in the 
914 exhaust is M8..? 

  I have a recollection that mine are an AN thread. 

  I may be wrong.
