Found heater cores for sale at buypartsby.co.uk but they do not show an email contact address. They also don't show any information on whether they will ship overseas (to New Zealand)was wondering if some kind soul from the local area could give them a ring and ask for an email contact address so I can get in touch with them. Here are the details from their site.
For all enquiries please contact our sales desk on 0115 983 5280
Lines open Mon - Friday 9.00am to 5.00pm
I have asked on here recently about places to buy heater cores (sometimes called heater matrix) but as of yet have had no replies.
Thanks David
