Well, since this is such a hot topic, I figured I'd post what I came up with.
I used the stock mount location on the back of the manifold - no new holes to drill, plenty of room, away from any direct heat.
I used aluminum channel and flat stock to make the bracket. The reason I chose to use the channel is so it can act as a heat sink. I bent up the flat stock to facilitate attaching it to the manifold bosses. I got stainless fasteners to prevent corrosion after heat cycling. All basic hardware store stuff, like $25. Similar price to a buying a bracket at a parts store but this one is made to fit.
My fabrication skills are a little lacking but you get the idea.
Hope someone finds this useful.
