My 1990 XJ-S has two steel plates under the bonnet which are riveted to the underside of the bonnet itself. On them are three informational decals. The part numbers of the decals appear to be ECB 2681, ECB 2682 and ECB 3695. They were disfigured by a leaking air conditioner compressor and need to be replaced. Does anyone know of a source for replacement decals? Thanks!
