Linn Akito 2B mounting template..

Anybody got one? I bought a nice near new Akito arm here but the vendor bought it with a new Sondek and had no template. Mounting it on a SOTA Star Sapphire, with the armboard drilled for an RB300. My drafting skills might be okay to get the three screwholes right but would rather be exact. Looks like I'll need to countersink the screw holes too, they're shot-ish for the SOTA armboard....
