I know I have a spare junk intake mani. I might still have a junk Chinese Weber, I'll have to check. I was going to pick up that K&N plenum anyway. I can ship that stuff to you to use as a jig.
I suggest making a few extra kits and putting them on eBay so the Kiwis and Aussies are exposed to them. Or at least gauge interest in them on their message boards. They seem to love turbo carby setups down there. Maybe Geezer would know what the market is like.
