Before I had to park the 66 Lark 8 years ago, (due to not receiving a title, long story) I remember reading a thread here that a guy made an aftermarket detent for the ST. Although I seem to remember he was a Olds guy. It worked off of the brake lights, intake vacuum and an adjustable timer. Anybody remember that and/our how to get ahold off him?
You are talking about the SP control box made by Bruce Roe. He is a member here, http://www.v8buick.com/index.php?members/bruce-roe.27974/ http://www.v8buick.com/index.php?th...ol-boxes-still-available.267608/#post-2199968 http://www.v8buick.com/index.php?threads/switch-pitch-wiring.251643/ http://www.v8buick.com/index.php?threads/switch-pitch-tranny-controls.212509/#post-1708030 Post #8 in the above thread has a word document you can download in post #8. It goes into more detail about my experience with the control box.
