First A2s had the tools all the the right part of the foam unless a tow bar was ordered from new. In that case they fitted the now normal shaped foam with the tools along the rear and the cut out for the tow hitch. Now if Bose was specified the tools move under the right front floor but do not remember seeing a tow bar storage under the front floor and not obvious from the foam either. Sure someone will comment to correct this.
So all A2s had the storage location built into the foam from quite early on as they standardised the foam. Just because you have the storage location is not a guarantee that the tow bar was / is fitted now.
