I agree you can use a Fiat latch and they run about about $20. Check out eBay Italy.
but the Fiat version seems to vary in one small area from the OEM Pantera version.
note the bottom release latch arm in the two photos above, one having one hole and the OEM Pantera unit having two holes
The arm profile is also different but other than that the latches do appear to be exactly the same.
