Crank Sensor Replacement--Help! in Buick Reatta Posted June 25 On 6/21/2021 at 11:39 AM, MRJBUICK said: my 91 is adjustable like said above carefull, slow, dillegent work you can do it like the matchbook idea, remind's me of points lol I don't usually do this but, I will ask you to point out the adjustment point for me. Keep in mind I have bolted on at least ten of these. Not once have I had to adjust it. Also it is the same part across all Reatti years and supercharged series one motors.
