964 cam sprocket offset spec?
I am swapping cams on a 964. Does anyone have a spec for the offset value between the cam sprockets and int shaft?
I have the measurements but not the offset spec. I think it is different than the usual 911 (up to 3.2) value. Since these are different cam blanks I want to make sure the sprockets are shimmed correctly. Thanks

I don’t have the spec but the intermediate shafts are interchangeable so the 3.2 spec and set up should be the same

Found the spec.
For reference: Measured from Int shaft face to cam sprocket face. Right side (passenger) target 78.77 +/- 0.25mm Left side (driver) target 133.57 +/- 0.25mm. I realize the factory just says to count shims. Not good enough for me since I swapped out cams. I needed to measure. Right side is 0.06mm off. Yeah! Left side needs a 0.50mm shim.
