Hi Alan,
I really doubt if that year Jero is actually fitted with converter. We have resonator in silencer assy here as a compulsory but cat and cat back is not must. You can give a call to spare part dealer listed on home page under business listing here and see if they can search cat for your car as per your car VIN number.
Alternatively, other way around is you can buy UK or french Jero cat and cut the pipe and get it weld (old style), that will still work even if its not a proper bolt in solution and will get your MOT passed.
