After much searching I came up with no answer so I ended up getting the venier calipers out and measuring the distance between the bolts and the distance to the outside of the bolts. I calculated the diameter of inside and outside of the bolt circle and came up with 79.5 & 101.5 obviously there is some measurement error there as the bolts are M10 but feel pretty confident that the pitch circle dia would be 90mm I put a bit of polycarbonate sheet on the mill and drilled three 11mm holes on a 90mm PCD and checked that inside and outside diameters fitted in the holes
