An update on my dealings with this guy for those that are interested.
Classic Wiring Looms no longer operate as a business, so no chance of anyone else of getting messed around by this guy.
I got a refund of the money I paid & the under dash harness was returned, but my engine harness was not. Even though I got messed around for 8 months & lost my engine bay harness, I guess I am kind of lucky, now I need to find a replacement harness with firewall plug & get the whole lot off to vintage harnesses & start again.
Cheers Vic
