There are two parts your description could be:
Subframe spacer part no: 159211

or
Anti-roll bar spacer part no: 153683 (fitted into the front strut of the lower wishbone to prevent the anti roll bar link 153735 from crushing it when tightened).
This is a Dolomite part, I'm not sure if anti roll bars were fitted to Toledo's in NZ, but they were not fitted to any UK cars I am aware of as original equipment, though of course they do fit due to the nature of the BL parts bin.
