I bought a small right angled drilling head from Maplins and got a drill made up in work to fit the chuck which I can do the same for you and send it on if you wish. You can buy a tap wrench and tap set from Halfords or a local motor factor. You would then just need to buy the mount/bolts from Vx and buy yourself a polybush. You could either just get your welding chap to fabricate some brackets or do as I did and troll ebay for someone breaking an Astra or Zafira and get then to cut out the subframe section where the mount bracket are.
Its just a case of drilling 1 hole that is already marked on the bell housing, tapping it out then assy the mount to the housing. Once this is bolted in place you can see where you need to attach brackets to the subframe. It took me weeks of messing about trying things out but we got there eventually.
