HJ Front Indicator Bezels

[HK1837]

HZ catalogue list the same part number ie 9936753 & 4 for all HZ. For some reason they all supercede to 92001405 & 6 except for Ambulance?

HX are all the same too and same number, and so are HJ.

Those part numbers you put up Blocker are non existant in any catalogues, so I'd say they are drawing numbers for the unassembled plastic base and not a part number for the whole assembly.

My guess is the revised 92 part numbers are the ones without the chrome, and these were probably aftermarket parts provided back to GMH minus the chrome bits.

EDIT: Looking at later HZ they appear to be missing the chrome bars as Nocturne says, but it looks like the early ones had them and Ambulance kept them too. So probably a cost cutting exercise at some stage in HZ when they changed part numbers.
