Now cars with disc brakes on the front have a wheel cylinder with two pistons, affixed to the backing plate by means of a C-clip, and the hand brake lever is totally seperate and operates on the brake shoes not the wheel cylinder. Does this describe what you have?
There are a number of manufacturers of these wheel cylinders - some use normal rubber cups, some use your Polo mint seal. There are even different versions of the Polo mint - same OD but different ID, depending on the whim of the manufacturer. The one thing they all have in common is their overall external shape and dimensions, and their bore size. They are all 3/4" just like on your car (so if the supplier sent 7/8" cups they're wrong again). The internal pistons are all interchangeable, but the seal kits are not.
You will probaly need to buy complete new wheel cylinders. If the internal bores in yours are perfect, just swap over the pistons with seals. Otherwise, swap the whole cylinder. They're cheap.
hope that helps, and avagoodday
