Sure you can contact him through ebay, I did for the grommets as he doesn't respond to pm's on Turbosport.

Ebay user nam is m00gle he's selling off a lot of stock, cosworth loom plugs full set for £38 buy it now,

Hope this helps.....I'd seriously do your own, it's cost me £200 so far and that's with the tools and extra plugs and pins. I'm actually enjoying doing it as well
