It isn't just the dash pad that changes with HZ C trim over V though. From memory the HJ-HZ W, X, Y, A and B trims are called Caribou (I assume because the vinyl grain is a replica of a Caribou leather), not sure what the C vinyl grain is called. I think HQ was Roebuck but can't remember for certain. I don't recall seeing many or any WB's with C codes but they are listed in the WB parts catalogues so maybe only the early ones built prior to VC volume production?
