You have to get the hubs machined where the shock bolts to them by 2mm either side so that the shocks will fit and you'll also have to either drill the holes in the shocks bigger or fit some sleeves into the holes in the hub as they're bigger on 172 items

The other option if you want to use 172 shafts is to press out the hub flange from the mk1 hub & replace it with the 172 hub flange as the spline part of the 172 shafts are bigger than the williams ones
