Those anchor bolts are huge. I also found that my concrete slab is 9" thick. You need at least 4" they say, but 5, 7/8 is ideal. Some of the newer slabs around here are full of polystyrene!@
Have bolted in the first column and done all the measurements with the Cobra and the other car to ensure that the lifting arms are in the best position. Will fix the other column tomorrow morning and then fill it up with AFT fluid. Seems I can leave both columns there and still park the other car. I can also remove the RHS column in less than 5 mins and wheel it over to the side of the garage. The system has lots of flexibility in fitting, very good instructions and videos and high quality bolts. The hydraulic fittings are also pre fitted with either teflon tape or Loctite.
