Complete rear anti roll bar clamps/rubbers kit

Hi, new to the club despite having owned my 1983 Gti since 1986 - I'm not sure if this is the right forum section as not desperately urgent but can anyone recommend where to buy complete inner and outer clamps and rubbers for the rear anti roll bar

Heritage do them:
