Steve,
Just use the standard motor - it works fine (well. mine does).
Could you please not Shout?
Cheers,
Colin

I believe you don't even need to swap the wires around.

When I changed from pos to neg, the wiper motor was not touched. It is fine.

The wiper motor works either way round - do NOT change the wires round. This could cause a dangerous short circuit. If the wipers do not park correctly you may need to adjust the parking position.

It will work fine - since both the field and the rotor are being reversed - it will still run the same direction as before.
