"Winstonbike"
This is your latest and #8 post and you have yet to follow up on any of the other questions you asked and people replied to.
You also haven't supplied your name ... are you shy? Where are you located? You can make these changes to your "Profile" without risk of identity theft or worse ... a Dorki engine raid! We are a friendly group around here and most know each other face to face. Introduce yourself a little. Have you come to eny events [very loosely used term here
] where you met other Dorki?
From the sounds of it, you seem to be getting the itch to get your '67 912 on a track [eligible for an event]. It is already eligible for any PCA driver's ed event, concours, etc ... [assuming PCA membership] What sanctioning body are your thinking of where '68 is a cutoff?
Tell us a little about yourself and your car [pictures] and you will get a warm Dorki welcome and probably plenty of unwanted advice
