With all of the header talk around here, you might be interested in this. A buddy of mine has gotten a set of stainless steel header flanges made up and has a batch of 10 ready to be shipped out. He also has mild steel flanges for sale as well.
3/8" stainless steel laser cut header flanges.
For more info, PM me or email edethloff@mindspring.com
Starting prices are $140 for the set of stainless, and the price will go down as more orders are made.
The top is a mild steel and the lower is stainless.
