newbie, 1976 KZ900 police & 1973 Z2

Hi all,
New member in UK. Especially keen to contact members who have early 900 police models. Have an old CHiPs model which will be restored over the next year or so. Any advice appreciated.
Also keen on the Z2 models.

Don't know much about the early C models but there are at least two members with 1973 Z2's and at least one other with a later model Z2...that said...damn rare bikes!
