I haven't been able to compare the VTi mount points,to the USDM rex mount points,but everyone says they are different so you need the mount kit.I'd say they are the same,but it won't clear the US hood line,so you'd have to trim the ribs under the hood.IMO you could get the mounts from HAsport and then do the swap with both sets,the stock ones first to make sure then sell the HAsport ones if the stock ones work.If the stock ones work,then you can use the axles,shiftlinkage.
